I have a fresh, exceptional problem Samsung ativ publication v touchscreen 14" ultrabook. Purchased from Microsoft keep and still under service warranty. Has the i5 processor with 4gb of ddr3 ram upgradable to 16. Has a 500gb hybrid hard disk drive with home windows 8.1 escaping Strong state makings boot times very fast. The pc has a light weight aluminum body which makes for superb build quality and a back lit keyboard. I purchased an ipad as an alternative as I am on the go all the time. Supplies a good 6.5 hours of battery life too.
