iPi

The availability of small cheap (~£10) screen components for the Raspberry Pi is a great solution looking for a problem. It's called an iPi, because it's like a iMac, er, sort of.

The screen is ok, at 480×320 it has a 3:2 aspect ratio and 165ppi. The viewing angles are not really close to current mobile phone standards, but are ok. The best docs about the screen seem to be on the LCD Wiki at http://www.lcdwiki.com/3.5inch_RPi_Display where it is described as having the SKU of MPI3501.
