I can't find anything for any C290's that are going to have more than 2GB... I found that there is a apparently a 1GB model... Any news on any larger capacity models?
Probably the Teclast branded ones will only be 2GB max. However export models created by the same factory might have 4GB (like the C260 and C280's that are sold on futuredaps.com!)
Teclast should really release an 4 and 8gb(if possible) version. Because people want more capicity nowadays. 2Gb is fine for me, but I really like to have 4gb.
