You can't play the waiting game in tech forever. There will always be something newer. Once the Surface 2 is released, people will be talking about the Surface 3, then the 4. You've got to decide at some point. Every six months in the tech world, they will always be introducing the next newest and greatest thing.
I know this too well Working as a Sprint rep it drives the point home seeing new phones churning out all the time. Having previously been obsessed with cutting edge desktops, I'm familiar with the idea... I guess I just wanted validation that it would be worth waiting for the next Surface since my upgrade from the Samsung slate to the Surface Pro wouldn't be a big jump. Going to the next Surface would probably make more sense financially and hardware-wise since the difference would be greater.
I kicked myself when the Surface was announced.. but as you said, new things come out all the time. I just got a bit itchy this past month with the Pro arriving soon I made this thread to quell that itch a bit... it worked haha
