I was going to be childish and say you've missed the point, but I won't
Look, if you're doing lots of typing and multitasking, then a keyboard and more robust OS is a must, and absolutly you're going to get more work done on Windows than iOS.
However, "getting work done" was never the reason people bought iPads.
Its the experience, the convenience, the simplicity of being able to do 90% of the things you do on a computer in an easier, and dare I say it fun way.
Next time I have to write that 3,000 word essay I will absolutely grab my Macbook, the thought of doing that on an iPad terrifies me.
But when I want to browse eBay, or even sell something on eBay, or edit the photo's from my holiday, i'm picking up the iPad and lying back on the sofa.
...Where were we... I totally got off point.
Point is, specs don't make the iPad what it is, it's the experience.
The experience of putting a word document together is probably better on the Surface.
Yet everything else is yet to be seen, maybe it will be a great experience, I don't know.
What it like to buy and download an App?
What about downloading an album?
How will the browser perform?
etc.
But my initial irk was, people say the Sruface will be better because it has a faster processor and more RAM, but it doesn't mean anything.
