I think the reason it's taking a while to be made is that they do need a sort of 'in between' OS... OS X is too much, and iOS is not enough.
Maybe the best way to go about it is one OS that runs on everything
Yep, I guess you mean Windows 10
Kudos to the op for his review. I, myself, am very excited to purchase a S3 next week. I was out a Best Buy a few weeks ago and was extremely pleased and satisfied with the S3.
I have tried SP1,2 and 3 and returned them all. The first (2) I didn't like the screen ratio. The SP3 was nice, but it just couldn't replace my laptop and was a little too big for a tablet. For me, the S3 is a perfect combination of everything I was hoping for in a Surface. I'm not looking for it to replace my laptop, but to supplement it. The S3 is what I have been waiting for. I think it will do very well in sales.
