Amazon does 30 days money back no questions asked.
If you really want to see the differences, you could order a HD2 off Amazon, do all the tests you want for 30 days then send it back and get a full refund.

Remember to get it directly from Amazon though, not through the 'sellers'

No matter how pretty WinMo is made, you still cannot hide the fact that its still WinMo underneath. I would have purchased the HD2 if it were something like Android. Although Maemo > Android

Erm... what are you guys mumbling about. Its not even real multitasking; most of the applications are paused when you exit them. Take bounce as an example, the game pauses when you exit it. Also I have yet to see a video of n900 running youtube without it stuttering. I would like to see a video overviewing all multiple tasks without them being paused.... Put 4 youtubes at the same time lol... forget it guys.

The mouse pointer seems to be poor aswell, seems hard to use.

Thank god, I don't want the game to keep running and ending with a big "GAME OVER" after I get back to it from a call.. hehe.. I do see it rendering the game even if you left it.. but its paused by design.

That is most definitely not the case. The applications that DO pause do it for two reasons: a) to conserve battery, b) to conserve a state (like the game example from other posts) on an interruption.

A big problem here is network caused delay. As funny as it may seem, my N900 stutters noticeably when there is FAST connection, my guess is that dowloading also uses the CPU, leaving less CPU for the actual playback. If you wait for the loading to finish, it's quite ok.

4 Youtubes at the same time stutter even on my 2.8GHz Core 2 Duo. Not sure about your point.

What part did you not understand? I could be wrong, since i actually dont own a n900, but from what i've seen you wont be able to actually RUN two youtubes at the same time. That is not hearing both audio outputs while watching one of them or to be able to watch both of them simultainously in the application overview. This you can do in desktop windows and that is real multitasking.

This is a clever choice indeed, but what if I want to multitask? Which was really my point. It does not multitask.

So if you cant download at high speeds at the same time as watching, how are you supposed to be able to multitask? Also, what do you mean by quite ok? It in the eye of the beholder but any stuttering would irritate me. Specially if I want to enjoy a movie (Ive seen that even divx quality video stutters on n900)

more poppycock.
youtube videos seem to stutter for the first few seconds on current firmware, but after than runs totally smoothly. As for video/div x show me a video where this is the case.

As I mentioned - youtube/the browser fully multitasks, as does bounce, as does the Mp3 player - tell me that isnt multitasking - this isnt a iphone mate.;) All you need to do is look at a youtube video to corroborate this, why are you bothering,

Why all the comparison and such with Youtube?

Youtube in my honest opinion is crap anyways. If you base a phone choice souly on Youtube you need to have your head examined.

Ok I admit this is drawing needles. I absolutely love the device and will prolly get it myself. My point is that people tend to praise the device more than it deserves. Yes it does play youtube, but not without stuttering. It does do some multitasking (in some sense, i.e., pausing programs) but not as one is used to do on a PC.

bounce seems to enter some semi-paused state. youtube clips are paused right? Mp3s does multitask yes.

no its not an Iphone, I didnt even bother signing an iphone forum... never liked it. Toy :)

The point is that there is no point in discussing multitasking if the phone is not even capable of playing youtube clips without stuttering (unless there is a fundamental software error / lack of optimization).

Any by discussing multitasking I mean in the sense of praising how powerful the phone is.

None of these n900 is running the latest firmware as far as I know.

Must be my English. The application needs to pause ITSELF. The OS won't move a finger to pause anything, regardless of what view you are in.

You can. I'm just saying it might impact framerate.

You should then not buy any mobile phones for such purposes. There is no mobile hardware available today that can display all content PERFECTLY under all circumstances.

That is plain wrong. There was either something running in the background (yes, that pesky multitasking), or you were looking at videos that are in a high-bitrate format that is not hardware accelerated. For example, the '9' trailer that comes with the device is 3500kbps MPEG4 video with 192kpbs AAC audio and it can be played back without stuttering.

So ? Are you expecting the N900 to overcome something that is not universal on desktop class hardware ?

first video - personally I cant see the stuttering, only possibly at the beginning when panning in the first second (caching??)

second video - its outputting to a 1080p TV, give it a break:p

third video is from September - early firmware - looking at recent videos you just dont get this stuttering at all.

Look Im not saying the N900 is the be all and end all but your comments seem slightly, well disingenuous really. It doesnt stutter youtube videos per say, it does fully multitask - look at this video and tell me it doesnt - just like a PC. http://tr.im/EVtr

BTW you *are* aware that while saying youtube, you are in fact discussing Flash, which is entirely Adobe's domain, and technically has very little to do with the N900 and Nokia in general ?

EDIT: And, note that nearly all stutters 'demostrated' in links above are more likely the result of multitasking. If the N900 has a problem with multitasking, it's that it can't be turned OFF. :)

Ok guys I give up :) It does multitask... But its good to be sceptical and critical, which I was....

If it does download a podcast while playing an mp3 while I surf the web with the browser with an IM client receiving messages... yes, that's multitasking...

Your example is meaningless, the fact that some kind of multitasking is too cpu-heavy does not mean that the N900 does not multitask...

yes you are right. I believed that it paused applications except a few (such as mp3 playback) but I was wrong :P

i read this statement more here and there.

Why do people think that? SSD is not directly faster then even a notebook hd.. Yes ofcourse if we talk about real SSD harddrives like the Intel G2 or the Vertex of OCZ then those are really faster. But those have multiply channels access (up to 10) to many pages of flash.. That does make ik really faster. I cant believe that the controller thats inside the N900 is that advanced.

For example just put in a usb stick or a sd card in your laptop. do you really think that is faster then your normal hd that you have in your laptop? (i am comparing it to laptops here because desktop drives are even faster)

I do have a Intel G2 in my laptop and yes thats really fast way way better then any laptop hd you can have. Its the best upgrade a person can do (in the last few years combined) especially in the laptop world. But i dont think we can compare that to the flash (controller) thats in the N900

Well there's your issue. Flash is by no way optimized prior to Flash 10 on Linux systems. Prior versions of flash relied on the CPU to do most of the grunt work regardless if you had a videocard or not. While Flash 10 directs the work to the videocard.

My dual core systems when in Ubuntu would always slow down on heavy flash video sites prior to Flash 10. Luckily the n900 seems to be getting flash 10 in 2010.

Rushmore 2009-11-15 15:55

Re: HD2 has 1ghz processor and 448MB ram, why not the n900?
 
The stuttering on the N900 appears to be due to a lack of pre-cache. That is a reason I would like to see Coreplayer on the N900, since it has adjustments for streaming video cache from zero to whatever you need.

Does the current apps have an option to adjust cache? Bet you the bank this is the problem, since when it gets going, the only stutter I have seen was when a demo had two Flash sessions going at once.

The stutter at launch is consistent in the demos I have seen, so it must be a missed parameter in the application build.

I have a Q8200, 6gig ddr3 and g9800 and sometimes vids lag, but it depends on too many other factors to assume it is a cpu, network or application problem. Too many combination without a control to orientate to a source of the problem and the 3430 is not a Q8200 with 6gigs ddr3.

Still, Maemo and the 3430 chipset is a better combination than snapdragon and WM. The N900 is also better off with the 3430 due to battery life. Snapdragon tries to do the same things the 3430 chipset does with extra clock cycles.

At least the consensus is this on most forums and tech links.

Even the slowest USB flash stick runs circles around the fastest hard drives when it comes to random access. This is due to seek delays of magnetic storage. Since swap is accessed randomly, flash memory is very well suited for it.

The internal 32 GB flash of the N900 is an eMMC device. It handles wear leveling and related stuff autonomously. It is not unreasonable to expect that the eMMC controller would also do parallel reads and writes.

It would be perhaps more accurate to say they have different characteristics and actual performance depends on the use-case scenario. In some cases one is superior, in others, it's the other one. Currently, IMO the N900 eMMC's weakest point is simultaneous small writes, that really kills performance. I would leave USB sticks out of the story as the USB bus/devices have their own limitations with regard to latency and bandwidth.
