Hello friends! Rohit here.
I would start with operating system. I as an engineer know some facts.I remember when the ipad was launched you had some five option to opt from. They were blackberry tablet OS, APPLES IOS, MICROSOFT WINDOWS, GOOGLE ANDROID AND PALM IOS. That time you has some three of them viable. If you needed windows, ios and adroid the choice gets simpler.
See a 7inch tab is really large in size. I do hace a apple tab. But u literally tell you I really don’t use it much. Buy it if you really need it. I would prefer you to buy a macbook instead. It has got some really awesome features. You nees not to logout. Just shut the shutter and open. You resume it from where you left.
Always go for the features available. And the most important thing is RAM. You must have a tablet of minimum 4 GB RAM. A 6GB would work really good. See the power backup. And the shape ofcourse. This 7 inch 7 would not even fit to your pocket then why not buy a laptop or macbook.
Rest all your decision.
Thanks!
