If your Surface Pro suddenly turned back into the wad of money that you paid for it, what would you do? Would you run out and buy a new one? Buy something else? Stick the money in your pocket and wait until the Surface Pro 2 comes out? Buy a MacBook Air? Other?
I wouldn't change a thing. I use my Surface Pro daily. I knew going into it that the SP was more costly than any other tablet. But I also knew that it was more than a tablet. So, I have no regrets regarding cost.
I did my research prior to buying the SP so I also knew the pros (full Win 8, i5 proc, 4gb RAM) and the cons (~4 hr battery, single position kick stand) about it. So, I no regrets about feature/functionality.
I researched all other available (keyword - available) alternatives. They were all some type of laptop hybrid that required some sort of twisting, pulling, turning, and transforming to go into tablet mode. Having had used previous Windows tablets (HP TX, Toshisba MX) I knew that, at the end of the day, they were still a laptop and I wasn't looking for a laptop. So, I no regrets about form factor but rather think that the SP has the best form factor.
Long story short, IMO, the SP is the best computer in tablet form factor. It does everything I need to do. I never expected it to replace my home computer so I'm not disappointed cuz it doesn't measure up to my home gaming rig. I waited patiently for the SP and bought it day one. It has not disappointed as I use it all day, every day. It is the only device (besides smartphone obviously) that I take while traveling. It is the only device I use at home when not doing hardcore gaming.
It is the best tablet I have owned and I have no regrets buying it and I would do it again. Course, when the SP2 comes out....
