That's exactly why I love my Windows 8 tablet: plug in a USB OTG adapter with a USB hub, plug in a Logitech mouse/keyboard combo, and you've basically got a computer. You can plug in external hdds, flash drives, sd card readers, speakers, anything. And then when you want a tablet again, you can just safely remove and unplug. So much more awesome than my Galaxy Tab 4.
Anyway, I got the Stream 8. It pretty much pays for itself with the 200 MB data for life and Office 365 deal. Plus, the 8-inch screen makes things easier to read.
