Nokia makes some small "tablet" computers that run Linux on an ARM processor. They fit in a shirt pocket. Originally the Nokia 770, then the N800, and the N810.
You can get a new N810 for $210 these days, and the N800 is comparable in every way, has the capacity for more internal storage, but lacks the built in GPS and thumbboard (but you can use a bluetooth GPS and bluetooth keyboard if you desire)
MaemoMapper is available free, and uses the GPS to show where you are, follow a route, tell you to follow a route, and so on. It downloads maps via the Internet, and needs an Internet connection to create a route, though not necessarily to follow one.
Download your maps and/or routes ahead of time, and you're good to go for an off-line adventure.
Maemo-Mapper now has APRS functionality built in, and if you follow the link above.. basically, this is a $210 touch-screen computer with GPS that you can hook to your KISS TNC and have a TWO WAY APRS device.
Nokia N810
MicroUSB to MiniUSB adapter
MiniUSB OTG to USB.
New PL2303 USB to Serial adapter
Null Model Cable
OpenTracker+ in KISS mode
ADI AT-201 2m handheld
Not just a transmit only tracker. Not a (useful and desirable, but still) text-based D700/D710 display, nor a $500 AvMap add-on, but a full color, 800x480 pixel display that plots other APRS users (and their icons) while also transmitting your location.
It will also combine data from an IGate and RF at the same time (and send your position report out to both at the same time if you desire).
If you happen to have an old Nokia 770 lying about, I think you can make this all work with it, too, but it has a slower CPU and half the RAM, and it will require a bit more patience.

Thanks for the info! Being a computer dummy stuck in Windows, I went with the Acer mini and Windows Pro ($289). Along with the TH-D7 HT and Deluo USB GPS. Nice to have all the features when on vacation. When in WiFi range or using the aircard, UI-View32, Digi, Igate, and APRS.FI for pan and zoom monitoring.

Not like you're hoping.
The N810 talks to the OpenTracker+
The OT+ talks to the ADI HT.
So I'm not using the N810 as a sound-card modem.
I'm using the N810 with a convoluted USB serial adapter to the OT+, with the OT+ providing KISS TNC services.
Picked up a few stations on my way home tonight using this setup, but still having a hard time getting heard - using the HT inside of the car. I should remove the 20m hamstick and put in a 2m antenna for a day or two.

Huh, That's a good looking gadget for that price. How useful is it in the wild?

I use mine all the time, but it is very limited in Ham radio use.
Much of the Linux software for Amateur radio use is compiled for Intel processors. The N810 uses a TI ARM compatible chip called OMAP. There is a lot of other useful software, including several map/nav programs (Maemo Mapper has an APRS function as the thread indicates), mostly free. I've not tried compiling anything since the bad old days, so I can't say how hard it would be porting an app over to Maemo, but I can't imagine it being an easy process given the major differences between "standard" Linux distros and Maemo -audio being the most obvious problem.
However, the OMAP processor and low system RAM make it a little slower than it should be. It does a great job with audio/video playback and basic web surfing, but as soon as you hit a flash or java site it bogs down, and while it does multitask OK, switching between applications sometimes is a painful experience.
This fall Nokia is releasing a new phone based on the Maemo platform, the N900. The early buzz is good, and if they keep it as open as the current models, I will likely get one. If it is popular enough, I could see ham applications developed for it, but not seeing much software on the iPhone store I don't know that there's much interest.

Well, it looks like I missed out on the sweet spot for the clearance prices. Too bad, as it looks like it would have been the perfect companion for a Tracker2 T2-301. Oh well.

I finally have a QEMU virtual Linux file with Scratchbox installed, but just as I was about to build MaemoMapper from CVS to get the APRS functions, they released the latest build with APRS built in. :)

I have a Nokia 770 with the slower CPU (240 vs 400 IIRC) and half the ram - the N800/N810 SCREAMS. :D
I routinely use mine to watch TV shows (recorded using MythTV on my linux HD DVR then transcoded into a NIT friendly format). My daughter watches "Dora" on some head phones while daddy drinks coffee with "the hams."
Back to the ham software - I use it with Maemo-Mapper, APRS, and my OT+ in KISS mode pretty often. I'm far more limited by the 5w HT transmitter and sparse coverage in Montana than by anything else.
