i guess it depends on how high priority the communication has in the "senders" 
mind. sms is very much a "when you have time" kind of system. im steps it up 
a notch via its presence system. and a phone call is very much a "drop 
everything else, NOW!" way of communicating.

ah yes. i forgot about all that. and yes, it would be quite the solution.

now that i think about it i have been pondering converting email into xmpp, 
given the recent interest in push email and all that...

as in, why use multiple protocols when one can use one?

indeed. but i cant say i have kept up to speed on recent developments. this is 
only something i picked up from wikipedia and similar sources, so...

hmm, pcmcia or expresscard? i recall early ipaq pdas had a sleeve for those 
kinds of addons that allowed the humble pda to access wifi and gsm networks. 
added quite a bit of bulk tho.

and was not a similar sleeve system bounced around for the neo? primarily for 
use with wifi?
