 A key thing here is the RAM, the 820 has 16 meg, the 720 32 meg and 728
64 meg. As people often don't have a swap partition (as it can destroy
flash memory cards) the amount of RAM really counts. I think the 7xx
series also have a slightly faster CPU and use a touch screen vs a
glidepad on the 820. The 820 is also physically larger than the 720/728
and is more like a mini laptop than a PDA. One key advantage of the 820
is that it has a USB host and can connect USB devices like mice,
keyboards, webcams etc while the 7xx only works as a USB client so the
USB connector is only any good for connecting to a USB host like a PC.

In terms of using Linux i'm not sure about the 820 but with the 720/728
you'll need a specialist flashboard (which nobody makes and nobody seems
to be able to find the parts to build their own) for full Linux support.
Without one you can't suspend while using Linux and Linux must be booted
from Windows CE. There are some hacks to help reduce this by slowing
down the clock speed, turning off the screen and turning off PCMCIA when
in suspend but this still leaves the problem that if you forget you left
the Jornada booted and didn't plug it in then it will drain its
batteries within hours. Also 2.6 doesn't work without a flashboard yet.

Have a look at http://jornada820.sourceforge.net/ and
