Best ultrabook for my needs?

[Dylan323i]

I have about a $700 budget, I do not mind going used via ebay and the like. My requirements are this, i5-i7 (preferably 4th gen for battery life) 8GB of ram, hybrid drive of some sort. HDMI port, backlit keyboard and a 1080p display sized between 13.3"-15". Also decent battery life (5 hours +) and slim profile (1" or less)

Thanks, I decided on the u510 as there were a few modifications to my needs. Great series of laptops though, now the only thing left to do is mod it with 4g lte connectivity.
