Hi,
Effectively, the next version will have 320x240 pixels resolution (more infos at Raisonance.com).
Like the Primer2 a square area will be reserved for application or system pages, and a second one for the toolbar.
The working area will be 240x240, so no problems for 8 bits coordinates.
The old applications will be binary compatibles (same API), they will work in a virtual 128 pixels centered screen box.
