I really like my MS Surface Pro 3. I don't now if it qualifies for the "mucho more storage space", mine has 128GB o storage and I have an additional 128GB of storage on a micro SD card.
I have a Nexus 7 Android tablet which I had before I got the Surface but since I got a Windows tablet the Android tablet mostly sits and collects dust. I don't know that Windows is easier to use than Android but I like being able to run the same software on my tablet as I do on my desktop and laptop.
