Ok, I'm getting an iPad. Mostly because it's a big ol' 10" screen iPhone 3GS.

Why? Because on my iPhone 3GS I can do the following:

1) Remote into home Mac via VNC FAST! ANd it works really well.

2) Stream AVI files from my home Mac to my iPhone over 3G/wi-fi flawlessly. (yeah, I'm in an excellent 3G coverage area). I just downloaded AirVideo to my iPhone and installed the AirVideo Server and in less than 5 minutes I was good to go. One minor router tweak and I could access it anywhere.

3) Stream all my audio files over 3G/wi-fi flawlessly. Pretty much the same method as stated in the AIrVideo point above.

4) Browse the web, FAST! No stutter, almost no wait times.

5) Exchange push email for work and my Gmail accounts.

6) VPN easily into client sites and our own colo and use SSH (Linux servers), or RDP (Windows servers/desktops), or VNC (Apple servers/desktops) to fix problems from just about anywhere.

I couldn't do any of that as easily on my N800 as I could on the iPhone 3GS.
I don't care about "multitasking", I care about "concentrating".
But hey, tell you what. I'll go head-to-head in the "fastest to VNC back to their home PC" with any N900 user. With all applications closed and sitting at home screens, put both phones in pants pockets and then yell "go!" and see which one is at the on-screen login prompt of a remote server via VNC first.
My 3GS will win every time.
I've played around with the N900 and it didn't seem as polished as the iPhone 3GS. I've owned an N800 and went away for an entire YEAR and a few weeks ago came back to it to see if it improved but it hasn't. Nokia abandoned it in favor of the N900, just like they did with the N770 and now the N810.
Beauty of it all is that every single app I've purchased or downloaded for free for my iPhone 3GS will work on the iPad right out of the box.
And FAST! With no lag. The N800 was "tap. wait. tap. wait." and I got tired of that real quick as it was wasting my valuable time.

Sorry gang, but Nokia burned me with the N95-1 and the N800. I don't want another Nokia product since it seems to quickly become unsupported in a year or two whereas with Apple they're still supporting the 1st gen iPhones and iPod Touches, even though they're slower and more underpowered when compared to the new line of Apple mobile devices.

Another thing most Nokia fans forget is that Nokia has pretty much abandoned the U.S. market. That's fine and all, and you can argue all day long how "great" it is that Nokia is selling phones in increasing numbers in the 3rd world, but I can guarantee you that if I walk into a cafe in a 3rd world country with an N900 in one hand and an iPhone 3GS in the other, more people are going to want to look at the iPhone. Why?
Well, hype is a big part of it but more and more people are finding that the iPhone "just works" as others in here have already stated. And word-of-mouth on the iPhone just spreads faster than Nokia phones.

I'm also pretty damn tired of having to hack a device to get it to do what I want - looking at you, Internet Tablets N770/N800/N810 and the N900. I haven't had to jailbreak my iPhone to get it to do what I want. I jailbroke my old iPod Touch to check it out but it was meh to say the least. My best friend back at UNC has that Touch now and he uses it for almost everything via campus-wide wi-fi.

Now, look at the development environment. Tons of books and guides out there for developing for the iPhone. Where are the books and guides for developing for Maemo? I guess they're only selling those in Europe?
Apple has made it so easy to develop for the iPhone that 3 drunken rednecks from Fuquay-Varina, North Carolina can make an excellent, well-polished, multiplayer 3D tank game in a fraction of the time it would take a Maemo developer of equal skill.

I lived in Germany from '95 to '07 and used to think "man, Americans are *****s when it comes to phones, they don't have anything like the phones over here. Europe's got it going on in the cell biz."
Then the iPhone came out and stomped any chance Nokia had of making it in the U.S. flat. All my friends in Germany now have iPhones.
I used to disparage the iPhone as being underpowered right up until the release of the 3GS when Apple said "meh, go ahead and do turn-by-turn navigation" and "oh look, Slingplayer for iPhone" and that's when I got an iPhone 3GS because those were two critical apps for me that the N95 could do that before the 3GS an Apple iPhone couldn't do.
How many turn-by-turn nav apps are there for the iPhone compared to any Maemo device? At least 5+. And in less than 30 seconds I can be on my way with turn-by-turn navigation compared to the 45-60 seconds it took my N95 running Garmin.

Face it folks, a polished, fast, easy-to-use UI with a excellent app store selection is what people EXPECT from a smartphone nowadays.
And Nokia just doesn't have it. You can scream all you want about the N900 feature-set smashing the iPhone 3GS but at the end of the day it's all about SALES NUMBERS and RECURRING REVENUES and the N900 just doesn't have it in those two key areas that every phone manufacturer wants to have.
All the potential in the world doesn't mean a hill of beans come end-of-quarter-sales-call.

And for those of you laughing at how Apple's stock price fluctuated, then you don't know the golden rule of playing the markets: buy on the rumor, sell on the news.
I did and made just enough to cover buying an iPad 32GB w/3G in 90 days. First time playing that game and I considered myself lucky and will never do it again because I'll never be that lucky again.

But hey, enjoy your "open source" N900 development environment. I'll be over here watching my N800 crawl loading a website "with flash!" while playing a 3D online multiplayer first-person shooter on my iPhone.

Remember folks, just like not letting your friends drive drunk, devs don't let devs develop for Maemo platforms.
