I have this computer for almost a month (version with 512 GB SSD). It works very well. Boots in 4-5 seconds. Screen and sound is very good. when doing normal office work (internet, wifi, various apps) on my lap (laying in the bed) the computer is very cold (no heating detected) and absolutely quiet (no fan sound detectable in quiet room 40cm away from the comp, only if I put my ear on the fan outlet I hear some tiny shivel), the majority of time; sometimes fan starts a bit more loud, but only for a while and still very quietly.
I tried also few games and works great. I tried Skyrim and Call of Duty Black Ops, the both at absolutely full details and all those graphics settings full, at FHD resolution, and works absolutely without any problems, very smoothly. awesome graphics. when gaming the heating and sound raises I was searching for business/gaming 17incher well branded for almost 3/4 of year, and found this as really very good option. I bought this computer with money-back option for 2 months, so i still have one month for testing, but I think, I will keep this one.
