After reading this 4 page discussion, all I can say is that early adopters ALWAYS bear the brunt of growing pains. As others have said, Apple devices suffer the same issues as Samsung, HTC and Microsoft. It's like buying the new design of a car. You never want to buy the first year of a redesign because there are always going to be issues, but in the case of computers, software and firmware updates tend to fix the issues that arise.
Yes, I have the same wifi battery issues as others have had and the pen was doing a few strange things in OneNote before I updated the drivers, but for what it is compared to the SP2, it's quite a feat to have a bigger screen and lighter form factor. My brother-in-law has a Surface 2 and he ranted and raved about it when he first got it and now he's oohing and aweing at my SP3. This replaced my work laptop and I foresee it to serve me well for work and personal use.
