In my opinion, no.
8gb one: 2.8" QVGA (240 x 320 pixels) Screen, built in 100mb storage + Built in 8gb flashdrive, black and has no camera lense cover.
Non 8gb one: 2.6" QVGA (240 x 320 pixels) Screen, built in 160mb storage, Silver and has a camera lense cover.
The 8gb version claims to have a better battery life but comparing my normal N95 with a few others including a couple of 8gb versions the battery life is pretty much the same which is rubbish lol
Standby time and talktime are pretty good on both but as soon as you start using camera a bit the battery soon goes down, one thing I really miss about my Sony Ericsson K810i is fact I could take a dozen or so pics do an hr or so phonecalls and still charge it once every 5 days, the N95 with same usage will need a charge within a day.
