Hi, I'm looking for a replacement for my laptop. I need a tablet with Windows 8.1 that can download software to the system (not Windows RT). I will use the tablet for Microsoft Office and watching videos such as Netflix. My budget is around $900. I was considering the Microsoft Surface Pro 2, but it is at the top of my price range without a keyboard and only 4gb of RAM. It does however have a 4th gen Intel processor. Any and all suggestions will be greatly appreciated
