Heya guys and gals - 
So after months (and months) of saving up I'm finally buying a Surface Pro 2 this weekend. WHOOOOO.
I plan on using this pretty much exclusively as a portable Photoshop machine so I can make my 
comics during times where I can't be at my home desktop machines (work lunch breaks, sitting at public transport, funerals of distant relatives, etc) 
I guess what I would like to know is - I figure that 128GB is enough room for Windows, a Photoshop installation and my Dropbox folder - but how does Photoshop perform with only 4GB of RAM on the Surface Pro 2? 
I have 4GB of RAM in my main W7 desktop machine and I don't have any real complaints about performance, but I was wondering if things would be much different considering Windows 8.1 and the tablet CPU / GPU. 
Also - how does the pen compare to a regular Cintiq? 
(I might also post this on the Arts & Farts thread)
