I've also got a Yoga 13 and I love it. (It runs Drive at 25 FPS ) The keys on the back in tablet mode aren't anything, people are just being nit-picky. You don't even notice it after you've used the Yoga as a tablet for a few hours. I also have the slip cover but it's more of an annoyance. I stopped using it after a while. The question is this: Do you want a laptop that turns into a tablet or a tablet that turns into a laptop? All of these "All in one" designs have a preferred mode, the Yoga 13 is more of a laptop for sure while something like MS Surface is more of a tablet. Ultimately, I'd say go for first gen Surface Pro if you're more of a tablet guy and go for the Yoga 13 if you're more of a laptop guy.
I might go for the yoga but I need the cheapest i5 configuration. I'm going to play world of Warcraft on it.
I'll probably be biting the bullet on a surface pro 2, if you need the keyboard you can get the 'Type cover'. They cost a lot though and they cost an arm, a leg and your first born child if you want 256gb space.
They both have the same spec. Pretty much all the windows tablets follow the same pattern of a core i5 running at 1.8ghz with 4gb of RAM and no dedicated graphics. There are a few newer ones that bump it to 8gb or 2.5ghz but those are out of budget, a few in your budget bump it *down* to core i3. None of them are better or worse than the others for world of warcraft. All are unsuitable for gaming although to be fair an i3 at 1.8 copes with world of warcraft as it is.
Between a pro 2 and yoga 13 then I would hands down say the pro 2. The pro also has a wacom digitiser whereas the yoga does not. Yoga only has a capacitive touch screen and can only recognise your finger as normal or you can get a capacitive stylus as a finger replacement, but that will still be treated the same as a finger. Surface pro has the capacitive touchscreen *and* a wacom digitiser touch screen, the wacom digitiser is a stylus based technology, but its highly accurate and also pressure sensitive (the galaxy note smartphones use a wacom digitiser for their fancy pens). One nice bonus of the wacom stylus is that the surface can detect the stylus when its hovering over the screen (about an inch away) so will disable the capacitive screen, the wacom layer cannot detect a human hand so with that disabled you can wrest your hand on the screen as you would on a sheet of paper and then write with the stylus. If thats no use to you then discard it as a one up, but that is a feature I personally would use and why my preference would be pro over yoga.
Already answered that one. CPU and graphics front they are equally pitted so neither will beat the other. Although if that is all you are buying a new machine for, why not just get a laptop?
