wah, a review, too soon for me actually, but a quick one may be possible, i hardly use the RT btw. Plan to trash it out in the coming weeks for a full review.
Surface RTgoodsBattery Life - 8 hours
lighter than Pro
as its arm architecture, RT will NEVER give you a blue screen
Connected standby- even when machine is on stanby, you still get latest updates / news feeds/mails upon wakinf it up
with 8.1 can join domain

free lync / outlook / word / excel / powerpoint /one note (savings of at least 600 bucks here)
badsneeds the original converter for vga - oem ones doesnt work
may be slower for multi tasking
unable to use x86 apps / relies on store apps
Surface PROgoodsa complete replacement for laptop - its my work machine now

discarded my lappy (lenovo X220T)
lovely screen resolution
able to use oem mini dp to vga converter to extend screen
runs all program from you usual desktops / lappies plus all in store
badsMax 4 hours battery life
Heats up pretty fast
Gotta pay for ms office

Heavier
Connectivity off when hibernating/sleeping to preserve battery. means apps dont get updated
So you do all your work in that 10.1 screen size? Or you plug to external monitor?
