Hello, I'm looking for a tablet to replace my phone and my laptop.. I will be using it for school, so it must be capable of running some kind of spreadsheet, text editor, presentation applications. (Google Docs(or drive??) will suffice) And of course since I don't leave home without my laptop, I came up with the idea that I wanted a tablet that had the capability of calling and sending text messages, using a 3g sim card. preferred OS, Android, of course...

any suggestions?
