Have a look at this tab , iZOTRON Tab 10.1 NKS101 1.6GHz Dual Core CPU IPS Screen 3G
It has almost everything that you want , including a top notch GPU , an IPS panel 10.1" screen , and 3G.
Priced at ~14k on Ebay.
Well come to think of it,...no... this do not have a GPS feature. And if you didn't like it and only want to buy the ones you shortlisted then i would suggest the Iball Slide.I think it don't have a GPU ....
and are you sure about the GPS feature?
The ones I listed earlier have similar specs .. y should i go for the one u suggested ?
14.5k for a iBall tablet?
All I can say is best of luck. You could have easily gotten a Galaxy Tab 2 for a bit more. Oh well..
OP has to make calls and I don't think any of the iPads whether new or old has this feature out of the box.Even the Galaxy Tab 2 stands no chance against the iPad...
