you have badly mistook an iPad for a laptop,
you should not expect a 'Tablet' to fit in your pocket, please go and buy an iPhone or a good android mobile
tablets certainly do not come with dvd drive
everything has to be synced nowadays, so this fact should have been known
and i accept that 16 is is less, you should have gone for a 32 gb or 64
yes, the new iPad is not really good except for the screen, so you should have gone for iPad 2, and India doesn't actually have 4G implemented right now, so it didn't really make sense choosing between iPad 2 or iPad
if you want to be a pirate and get free things for your iPad go and jailbreak
i have used the new iPad, and there was absolutely no problem with the touch sensitivity
typing on it is nice, have you tried to split the keyboard ?
you need a back button for what ? everything on iOS is app based, so the home button is enough, and if needed, then there is a back button in the app itself
you cannot expect any tablet to have computer like multitasking
safari is good to use, and i think they have tabbed browsing support for the iPad...
and remember, it is not a pc, you cannot run pc games like diablo
and please, now every charger is USB based -_-
there is a reason people make albums which act like folders...
you do not need a file manager as everything is stored as an app
for most of your other problems, iPad 2 was better
and really, you did not think before buying it ? read any reviews, read information or anything, most apple products are to be used under apple's limitations, if you can't live with that, sorry iDevices are not for you
