I will suggest you Sony Xperia Z2 Tablet. Want to know more about Go with this link : http://www.knowyourmobile.com/tablets/sony-xperia-z2-tablet/22113/sony-x...
The Internet is hard at work debating the merits of the Nexus 7 tablet, and the biggest arguments are about the lack of expandable storage, or an SD card, as you likely know it. It seems like everyone and their brother has a theory about why the hottest tablet to hit Android so far will be shipping without one. The most popular reason revolves around some conspiracy that Google is to forcing you to use its cloud services. While I'm sure Google would love nothing more than users depending on Google Drive or Google Music and there's certainly a big push for it that's not the reason devices have been trending away from expandable storage.
Thanks and Regards,
Although it hasn't been for sale very long, the Acer Iconia tablet looks promising. There are some good reviews on Amazon. Only $450 or so, making it cheaper than an iPad 2, but with a memory card slot and USB connectivity (which may still require an Android update to clear some bugs).
