• HP 48SX
• HP 48GX
• HP 49G+
• HP Pavilion N3410 (500 MHz K6-2, 15.1" active-matrix)
• Nokia N800
• HP 50G

Not counting the odd 4-function calculators (including a watch), and scientific non-programmable or non-graphing calculators required for some classes/tests (most recent & capable: HP 33s).

My chronological list, not including gaming handhelds:

1. HP48G - used as calc and PIM; resisted buying a belt pouch from EduCALC, but only just
2. HP48GX - expansion slots!
3. Compaq Contura Aero 4/33C - early subnotebook; established my maximum size for a notebook computer
4. Palm IIIxe - for which I did purchase and wear a belt pouch
5. HandEra 330 with CompactFlash WiFi - faster, QVGA, virtual graffiti, screen rotation, AAA or Li-Ion battery power, jog wheel, audio amp, dual expansion slots, and compatible with III-series docks, styluses, and peripherals--best Palm EVAR, except for near-guaranteed screen failure after a few years
6. Fujitsu Stylistic 500 - dual batteries (interchangeable with my Sony Mavica camera) plus internal bridge battery; expansion, hard drive, and RAM all on easily replaceable cards--should have started a trend
7. PalmOne Tungsten T5 - sole advantage over the 330: a working screen
8. Nokia N800 - my personal computer
9. Dell Latitude 1501 - bought as a desktop replacement & too big to be anything else; seldom used; less expensive than my N800

I've had a Franklin eBookman, a Treo 90, a Zaurus SL 5500, and a Zaurus SL C-860. And now of course my N800.

Oh well reminded, I had one of those too. Sold it though.

Various organizers.
TI-83 graphing calculator, if that counts
Palm IIIx (got refurbished really cheap)
Palm TX
Compaq Armada M300 (old subnotebook, got used)
N800

I've always had something of an obsession with portability and computing...when I was younger I thought organizers and whatnot were really neat and always wanted a handheld pc. Also, I've had a desktop for a long time so until recently couldn't really justify getting a full laptop. I got the old Palm IIIx to see how I like palms and how much I'd use it, then moved up to a Palm TX. It wasn't that great but I got a pretty good amount of use out it. After a couple of years, it got extremely unstable, and I was finally able to justify replacing it, and that's when I got my NIT (though I briefly considered an iPod Touch instead -- I'm very glad I chose the NIT).

In order? Ok..

Fun topic!

Visor Prism: A great solid little machine. The PIM was just great, apps started instantaneously, and Grafiti v1 was almost fast enough to take notes in class. Mine ended up dying after I overclocked it.

I replaced it with a Sharp Zaurus SL-5500, which had ok PIM apps and rather poor HWR, but made up for it by having a rather usable builtin keyboard. I really loved this formfactor for a PDA. As a bonus it played MP3s so I got to leave my crappy CD-MP3 player at home after I bought it. Mainly used for ebook reading, warwalking (all the rage back then. ), and very light web browsing with the included copy of Opera. I still have it and it still works for the most part, but the battery is almost useless. If I can get linux 2.6 running nicely on mine I'll be highly tempted to find a used one in better shape and a way to put a bigger, newer battery in it. Also, it beats the N800 hands-down for both one handed use and sunlight readability.

I later sprung for a Sharp Zaurus SL-C1000 which added a gorgeous 640x480 screen and USB host to the mix as well as a better keyboard and a faster processor. I got several years of use out of this, but it tended to always be in a state of kinda-sorta-working. Just recently (as in, the last couple months) the open source distributions for it have really matured, and combined with midori for web surfing it has become much more reliable and useful once again. This is the shining example for how a handheld keyboard should feel, complete with a nice d-pad. Nokia, if you're paying attention, grab one of these and copy the keyboard in it part for part!

In March of 2007 a perfect storm formed: My C1000 was being unreliable (software it turned out) and my local CompUSA was having a going out of business sale. This lead to the (impulse) purchase of my latest Linux/ARM device: a Nokia N800 at 30% off retail! The maturity of the software and the speed of the browser amazed me, and though 3rd party software offerings were a little slow to get going, the N800 has proved a really worthwhile purchase.

I wonder where we'll be this time next year in terms of Linux handhelds?

I've had quite a few devices and I've yet to find the perfect one yet, (as if that could really happen). They have all had their ups and downs. I have most of the devices, although I've sold some too. Usually I've acquired each device at a significantly lower cost then you'd normally pay, simply because the device has had an issue or two. So far I've been able to work out the issues and use the devices successfully. It's not been anything too major yet, so I've been able to fix at a low cost and without too much trouble. I have bought at full price, some of the newer items you'll see. I have a tendency for collecting old and new gadgets if you haven't noticed.

Laptops/Notebooks:

Averatec 3200 H1 - sitting around collecting dust and requires a new power board, since the connector in the back of the laptop is broken
IBM Thinkpad X30 - loaded with Fedora Core right now
IBM Thinkpad T41p - mainly used windows powered laptop
IBM Thinkpad X41 Tablet - picked this up for extremely cheap, person thought it was broken and all it ended up being was harddrive, memory, and a new screen, all of which I nabbed off ebay for fairly cheap

IBM PC110 - I regretfully made a stupid mistake and sold this. I wish I had never sold it though.
IBM Thinkpad 701 - fails in comparison to todays laptops' specs but damn cool was that butterfly mechanical folding fullsize keyboard.
Hammerhead Walkabout - greyscale, ruggedized waterproof tablet

Apple G3 Powerbook "Pismo" - An amazing rugged Apple laptop. It's awesome for taking notes and web surfing, email, and other light needs, and with two high capacity batteries I get over 15 hours, full brightness and wifi on. I still use it to this day for that very purpose.

Apple 12" G4 Powerbook
Apple 5300c
The Apple Portable (if you could really call around 15 pounds portable )
Apple 17" Macbook Pro

PDA's/Other Gadgets:
Palm m130
Handspring Visor Prism
Palm Tungsten C
HP Jornada 680e
HP Jornada 680 w/ ram expansion (essentially a Jornada 690)
HP Jornada 728
Mobilepro 900c - just bought this recently and really like the instant on/off of the device and the long battery life

Sharp Zaurus SL 5500
The original small Sharp Zaurus that was black and had the handheld pc form factor
Apple Newton Messagepad 2100
Apple Newton eMate
HP 50g - I'd consider this a computer with calculator software loaded onto it as powerful as it is
Texas Instruments 83 Plus Silver Edition
Texas Instruments 89 Titanium
8gb iPhone

Of course last but not least is the Nokia n800 I have recently purchased and really like alot.

Psion 3a - Still going strong
Psion 5 - until the screen died
Psion 5mx - until the screen died
Psion/SonyEricsson MC218 - guess what ... the screen died
... (tumbleweed rolls across scene .. I survive with just a phone for a year) ...
Nokia 770 - So cheap I could hardly believe it.

Wish list - N810 in a clamshell design (see Psion). To be honest I really miss the Psions. Solid PIM, great spreadsheet, simple cardfile database, good PC sync, excellent phone management (over IR), I could go on. Still my 770 is a lot of fun and will get at least a few more months usage before my next toy.

Cheers,
John

Mine are similar to johnpad's:

• Casio digital organiser - was very young, but a very limited computer in my pocket :-)
• Psion Series 5 - sold it to get a 5mx
• Psion Series 5mx - worked really well for years, until an incident with a door knob in a crowded corridor cracked the glass screen
• Psion Series 5mx - worked really well for a year or two, until an incident with a small drop cracked the glass screen
• Sony PEG-UX50 - my first experience with a PalmOS device for longer than a short play. Nice enough hardware, crappy OS. Very disappointing after a Psion.
• Psion netBook - well, a Series 7 which I upgraded. Very nice, but by this time the limitations of EPOC were becoming apparent (poor SSH, poor web browsing)
• Nokia 770 - very exciting, sold to buy...
• Nokia N800 - sold to buy...
• Nokia N810 - ...still wanting the productivity apps from over 10 years ago in EPOC :-/
