I'm glad a couple of people have had good experiences with the ux's touch ..googling sony vaio vgn-ux280p nets some of the most hits for the 180 up....and touch is one of problematic issues that seem unresolved.

I myself have been hovering over the "buy" button for a 180p ..
..throw on antix and away I go ...
antix'll run on a 1950's toaster...
so it would do well on the ux series I'm sure...
but those issues made/make me hesitate...

and yeah..
removable battery...
(so the battery life ain't the greatest...)
form factor...
proper audio in/out ports
touch (wish for more input from those who "have" no probs)
it does make it pretty good option...
regardless of age.

the current modern alternatives are ugly at this point ...ihell, buttdroid...or a literal raspbrick...
