Question: Kindle App Ipad versus Windows Surface Pro

Ladies and Gents;


currently I am reading on an Ipad 2. My laptop conked out last year and I tried to do work just with my Ipad but found that when traveling for longer than a weekend and needing to work, the Ipad is too cumbersome. My IT staff came up with several options, one was to get the Windows Surface Pro. I went to the store and tried the keyboard (I am kind of picky there) and I guess I can get used to it. However, do I really need two tablets? 


Has anyone tried the Kindle app on the Surface Pro?
