questions on Tablets/Ultrabooks?

[Maya]

Most tablets, ipad or android or microsoft, supports bluetooth so you can use wireless bluetooth keyboard with them. If you are looking for something light, you should consider mac book air. It's light and you can find more useful app for your study. You can also run microsoft office on mac. If you set on tablet, nexus 10 or samsung galaxy note 10.1 are also good. But I don't think they came with microsoft office. Depends on what other things you want to do with your tablet, check out whether the softwares are available on Surface.
