I'm in line with Graham's views. I've only had mine for two weeks now, but everything seems to work seamlessly. I'm still occasionally using the mouse because the touch sensitivity on my screen and mousepad is very light and quick and a brush in the wrong direction will take you to a different program real quick. I toyed with going with the Surface Pro 2, but I feel the tablets have still a little way to go to compete with a laptop, IMHO. My new laptop looks and feels like my old one, so all I have to do is adjust to the touchscreen. Only drawback is that the screen constantly needs cleaning - curse and a blessing at the same time.

I think if you like Win7 and you're thinking of replacing it on your present equipment, I don't know where the advantage would be. Win7 is a pretty solid OS. I only went with 8.1 because I needed a new laptop. I hear MS is already looking to address issues with the start tile page vs the desktop - I like the tiles, but I miss the familiarity of the desktop and address bar access. I'm still learning and maybe some readers here can direct us neo's to a good source book or tutorial.

If you're going with 8.1 don't get anything less than 8gb RAM. I have a 1T HD and several USB for offsite storage. Check the I-core5 chips; there are two, 3373u(?) and 4200, which have some performance differences. If that's a biggie for you, read up and decide before you buy.
