the next web reports RT starts @ $599, Pro's start at $999
Please note, none of the following has been confirmed.
Today, a source close to Microsoft has provided us with corroboration of rumored Microsoft Surface pricing, putting the Tegra 3 powered RT model at $599 retail and the Ivy Bridge packing Windows 8 Pro model at $999 retail.
This puts the RT as a Direct competitor to the iPad, and the Pro as a direct competitor to the Air. This changes the windows 8 landscape in my eyes by quite a bit. Take also into consideration the bloomberg report that the wifi only would be the debut model and the picture gets clearer still.
Do these later breaking details change your view? It's going to be an interesting Summer!
