right now the only one I know for sure you can get is the p8860 from ebay. It is the same but it does not have the 3mega pixel camera on the back or 3g modem. It has wifi and all the other stuff though.

The p8888 and gigabyte m528 will be available some time in Jan or Feb from http://www.expansys.com and http://www.mobilx.hu

These will run you like $700 though so prepare to shell out some serious cash. I would wait until nokia releases the next tablet though because it will probably be better and cheaper but you never know.
