Simple question. What have you used until now. What do you think of the devices?

My list is rather long with lots of different devices. So:
Tablet PCs
Compaq Concerto - Long, long ago. I think it was 1993 or 1994. 386, 4MB RAM, Greyscale. Win 3.11 for Pen. Laptops were a rare back then and nobody had even heard of tablets. I was astonished by the handwriting recognition, Notebook application (a real notebook!).
Toshiba Portege 3500 - More recent one. Awful case (it was cracking like a waffer)
HP tc4200 - My current laptop. Great for using as a notebook. I haven't used pen'n'paper in months

PocketPCs
Dell Axim X5 (400Mhz) - 3 years ago. Again I was amazed by the fact that I had a 400Mhz computing device the size of my palm.
HP rx3115 - First WiFi device. Astonishing. I walk around and browse at the same time! Otherwise really underpowered machine.
Dell Axim X30 Mid - PXA270 is still THE pda processor. Unmatched speed
Fujitsu Siemens Loox 610/BT Big device. Really big. And the BT abtenna made it look like a phone (a big phone :-D) Died from overclocking. AFAIK this is the only PDA that can die from overclocking. I have did it on at least 6-7-8 other, but as it turned out later (I know for 2 o3 dead from overclock too) this specifik model has some problems with the mainboard
Dell Axim x51v - 624Mhz CPU, 16MB 3D accelerator. Again fits in the palm. Quake 3 running while waiting for the bus. The CPU ran rock solid stable at 1014Mhz. In my palm. Lol.
Qtek S100 - My first and only PDA with GSM functionality. It turned out to be pretty handy.
Motorola MPx200 - Not really a PocketPC, but it runs Windows Mobile. It is invincible! You can flash it with a random series of 0 and 1 and it can be resurrected in minutes! Originally with WM2002 there are unofficial ROM all the way up to WM6.1

UMPC
Gigabyte U60 - My only (yet) UMPC. VIA C-7 is Slow. Really slow. It was a great machine, the idea is great, but the price... It's too big and expensive to be used as primary PDA, and again is too small (and slow) to be used for serious work. Entering something like one page of text with the built-in keyboard...

Internet Tablets
N800 - I had two of them for a few months each. Great machine. Big screen, and yet it is "pocketable". Linux (see the end), great for both browsing and multimedia. I would get another one soon!

Other
Privileg M800 - A wrist watch/phone. This is the device with the greates LOL-factor I have ever had. Nobody even suspects it's a phone until it rings! Touchscreen, Stereo BT, 128MB memory, stereo speakers, and is just a little bigger than a sports watch! (Picture

Sony PSP (Phat) _ It has a CPU, Memory, Linux can run on it, so it counts. Astonishing graphics, alful web browsing, great screen. For games and movies - great. A little bit big for a MP3 player and I don't really like the music player.


I think that's all. Every one of them has it's own pros and cons, but the most usefull seems to be the HP tablet pc, as I use it is the most usable. Not the most mobile/cheap one, but I use it for almost everything I have used any of the other devices.

And about OSs, I have used Linux on all the devices that support it in usable way.

I had several cheap Palms.

My favorite portable computing device was the Rex 6000 -- Wikipedia article here. I moved to Russia with it literally in the credit card pocket of my wallet.

I would buy something with that form factor again. Now instead of having a cradle it would be wireless, of course.

I'm also a fan of the cheap palm. I still use my Zire 31 to listen to audiobooks. (Something the N800 can't do properly yet). I was given a Treo 600 that I used for quite a while, but the earphone needs special jack that I keep losing, so I went back to the Zire 31. I like the Palms instant on and off and its durability. If Palm had actually built and sold the Folio, I probably never would have bought the N800.

In an obscure past, a TI-57 pocket calculator. It was amazing for me - I was a boy.
The venerable Sharp PC-1500 pocket computer - year 1982!
More recently, the whole nokia communicators and tablets series: 9000, 9110, 9210, 9500, e90 + 770 (sold), 800, 810.

my portable history:

tandy cga laptop -> psion series 3 -> amstrad NC100 -> psion series 5 -> zaurus SL5500 -> zaurus C860 -> zaurus c3200 -> nokia n800 -> nokia n810

also had some laptops and TI89/92's along the way...

Sharp PC-1500 -> Palm m501 -> Palm T5 -> N800
Several HP laptops along these years

If we are talking early stuff, I still have my Casio CQ-1 (1976)

More or less chronologically: Psion Series 3a, HP Omnibook 425, Palm IIIc, Psion Series 5mx (2 pcs, 1 Pro), Newton MessagePad 2100 (2 pcs), Fujitsu Siemens Tablet ST3400, Sony Ericsson P910i, Siemens SIMPad SL4, Nokia 770, Fujitsu Siemens Tablet ST4120, Nokia N800, Pepper Pad 3, Psion Netbook.

That's about it for now.

a 386 no name laptop, a 750p ibm thinkpad (486), casio gfx 9850g, handspring visor deluxe, sony clie sj22, toshiba m100, nokia e61, nokia n800.

cheap slide rule, ti33e, nokia 770 , nokia 810. I wonder where the border line for computable devices llies. I had one of those microsoft-timex watches that you could sink buy holding it up to the monitor. that was the weirdest.
