To the other three guys (or gals)....
... who own a HP Jornada 720 and are using Opie on it and they have the spanish/latin-american keyboard... here is your keymap.
I will write something about how to get Linux going right on it soon, but here's the status report, 48 hours in.
This baby (unnamed yet) has:
32MB of RAM
1 GB of Flash
Wifi (802.11b pcmcia) + IRDA + Ethernet (pcmcia) + Anything once I find a 16-bit pcmcia-USB card (anyone has a spare and wants to recycle it? ;-)
Decent battery life (6 hours use with wifi, 9 without)
A decent screen (640x240)
A decent Linux-based GUI (Opie)
A somewhat erratic touchscreen
So, what can I do with it:
Web browsing ( With Konqueror goodness )
Programming (Python, even PyQt2!). They keyboard and screen are surprisingly decent.
eBook reading. This is the most important one. In my work, I spend a lot of time waiting. Waiting for the train to arrive, for the trip to end, for someone to come to a meeting, for the waiter to bring my meal, for stuff to compile, for stuff to download... maybe I wait 3 hours a day. So I read. And this screen (long and somewhat thin) is quite spectacular for reading. Opie-reader is pretty good.
MP3 and Video player (haven't used it yet). I have streaming TV at home, courtesy of CherryTV (check the links at the left). This should work great when Rosario wants to see Montecristo and I'd rather see Penn & Teller's show.
General PIM stuff. Although I tend to keep that stuff in my head and my phone.
The bad side:
The bizarre screen aspect ratio confuses many configuration dialogs.
Almost no game works unless you rotate the screen.
The keyboard configuration took a while, and is not perfect yet ( I can't make dead_acute work for some reason)
The extra buttons don't work (external audio recorder, and alarm light-button)
I can't find a way to bind the function keys to apps in Opie
The reset button doesn't work (it's now a hang button)
Suspend is not really suspend on Linux (for unavoidable hardware reasons), so it spends battery when suspended (may last 12 hours or so, I think).
The only way to really turn it off is to take out the battery (not as bad as it sounds).
If you do that, it takes about one minute to boot.
So, I am using it more as a laptop (although a really, really small one, with very, very good battery life :-) than as a PDA.
The small memory and CPU means I can't run very demanding stuff, but I never seem to do that, anyway.
And of course, the really bad thing: it's so much fun to hack with, I have trouble working!
All in all, a great toy, lots of fun, and rather useful.
