I own several non-phone Android devices (“tablets”, a netbook) and support some unofficial Google Wave dedicated to such devices.
Currently these are
1. Acer Aspire One AOD250 dual-boot WinXp/Android netbook.
2. Zii Plaszma Platform / Zii EGG StemCell Computer (multimedia device).
3. ARCHOS 5 Internet Tablet with Android (8 GB SSD version).
4. Camangi WebStation 7" Android tablet .
I hope to blog about comparative features of these devices soon.
