Its better to buy ipad 2 since its already coming out...unless you have an iphone4 then ipad 1st gen would be sufficient for studies...

i dunno...but ipod 4 and ipad 2 looks similar to me...just that its larger...and even ipod 4 i cant fully utilize it...therefore at this moment i would go for the cheaper ipad...with rm1599 u can get the 3g and wifi...but ipad 2 u have to fork out extra cash for the 3g function...
