Surface Pro's screen size concern

So after longing for an ultrabook/tablet hybrid since the Asus Transformer series, Microsoft's Surface Pro couldn't come at a better time.

It will be relatively light compared to ultrabooks, offer respectable performance, runs everything a Windows 7 machine can run, and has many use cases with its innovative form factor.

However, with its 10.6" screen, i am concerned with using it as a laptop replacement ( which is on the desk most of the time). Would it be too small to use comfortably from a distance as you would with a 14" laptop? Would it be ergonomic on a desk, where i have to hunch my back to type/ view the screen?

I dont live in the US, so it's be hard for me to personally try it - sitting down.

Hope to see some Surface RT users to shed some lights on this
