The Premini-II has a 1.3 megapixelvia . Battery life is up about 45%, too. Perhaps the most obvious change is the upgrade to a full 240x320 (QVGA) 262k color display with a 1.9" diagonal measurement, which replaces the old 65k color 128x160 unit. This display is really beautiful. Just as with the original So505i that Sony Ericsson made years ago, the display looks almost like a piece of paper - it simply doesn't look real. Engadget.
The Premini-II only has about 4MB of user available internal memory for storing photos and sound files, but it does have a shiny newDuo slot, something the older models lacked. With that, you can add up to 512MB of extra storage to the Premini-II, which should be more than enough to deal with its 1.3 megapixel camera and the associated photos.
