Waiting to see what can be done with a hacked 2.0.
i only bought my touch to Jailbreak it, i researched it for a couple weeks before i put out the money, but exactly 45 minutes after purchasing my 32gb i jailbroke it and installed what i needed. Un-Jail broken, it's a great M.I.D., but anywhere there is WiFi Access, i'm sure there is means of accessing your email/google, so to be blunt, it's rather useless with Factory Firmware.
And as far as 2.0 goes, It will definitely be Jailbroken/Hacked, very very quickly after it's final release, and as Far as 2.0 goes as Factory Firmware, i feel the same about it as i did before, Granted, they implemented a few new, interesting options and tweaks, but it can all be done on 1.1.4 already with 3rd party developments, and if it can't; It will be soon.
This is my own personal thoughts on the subject, and the usage i get out of my touch, which is a lot, and there are a few 3rd Party Apps, that if i couldn't use, i would just wipe my ass with my Pod and throw it in the toilet.
