Think the Surface Pro's are fantastic tablets. I own the first generation. Fantastic for artists and productivity and some light gaming too.
The 3 looks absolutely fantastic especially for what I need to be able to do on a machine. (3D modelling, sculpting and photoshop work)
Its a shame that most people hate on them just because its made by Microsoft. Some people need to mature a bit I guess.
Out of all the companies at the moment I see Microsoft really pushing for alternative ways to do things.
I also own an iMac, iPhone, iPad, Macbook Air, Macbook Pro and I think their great devices too and OSX is second to none however for what I need out of a machine and some of the programs I use only running in windows (3DS Max) the Surface Pro is perfect.
(Yes I know about bootcamp, I use it) but carrying a small lightweight tablet thats basically a powerful PC to do things like sculpt in 3D on the go is amazing to me.
I am the same - you will not find a bigger Apple evangelizer than me - I have a MBA, MBP, iPads Air and Mini, and more iPods than I can count - and Newtons, and iBooks, and Powerbooks...and I could go on and on. I count on Apple products for personal and professional use literally daily.
However...I picked up a first generation Surface with the full keyboard for under $200. Not only does it make what I considered a monstrosity, Windows 8, "make sense" for the first time, but it is an incredibly versatile laptop replacement that is not much bigger than an iPad and doesn't have all of the drawbacks of netbooks.
I have a second job teaching online, and it is so great to have a tablet-sized device that I can plug a mouse into and grade papers with a full version of Office. The iPad version of Office can't touch what the full one on the Surface does.
Even the v.1 Surface is an incredibly well-built device, and it appears that Microsoft finally gets it - controlling the software and the hardware makes for a compelling product. I dare say that most of you bad-mouthing it have never used one.
There is no way it replaces my MacBooks - and I love both of my iPads and update them yearly. However, the Surface is a really nice device; Microsoft has put out so much crap for the past two decades, let's give them a break when they actually get something right. It doesn't have to be an "either / or" world.
