I have been using iball slide i701 . its not so good but it can give you full pc experience . but screen is so small as well its display is so bad you should use it in dark place . you can update it from windows 8.1 to 10 . its having 16gb internal storage as well as 1 gb ram. battery not so good you have to connect it almost all time to power source. but its price is quite in budget in 5000rs and its cost is the reason to buy this tab otherwise I thing anybody should buy other device
