Choosing a calculator with a CAS.

Hello, I have been interested in use of CAS in high school and
undergraduate mathematics from
time to time and have just been reading about the new TI-Nspire CAS
calculator. Is anyone familiar
with this device? There does not seem to much independent evaluation
of it on the Web yet. What
are its CAS capabilities like? How does it compare to other handheld
CAS devices? There seem to be
several other competitors including another TI - the TI-89 Titanium.
The user interface on the TI-NSpire
does look nicer than the others though. Is there a clear best option
for a CAS handheld? Your opinions
will be welcomed.
