A move in the right direction, but call me a skeptic. Current Win 8 pro tablets have fans that are hardly that obtrusive and, as someone who has been a mobile PC gamer for over a decade, I've seen more than a few laptop designs that have heating that is *barely* adequate for the hardware put into the machine, if it could even considered to be so. I've had gaming laptops that were more or less only useable in basement suites or in the winter, and even then only when they were elevated in such a manner so as to have maximum surface area exposed.(I'm looking at you Toshiba Qosmio of about 2007!)
As for HP specifically, their current crop of tablets have less RAM and a general weaker component profile for the same price point as some of their competitors. I do want Windows 8 tablets without active heating involved, but I'm going to watch and wait until maybe the second or third generation of such devices before I jump in. As already stated, current gen tablet fans just aren't that obtrusive.
Also, get the price down. Full Windows 8 tablets are generally superior in functionality to iOS and Android devices but at 2 to 3 times the price, what the heck are these hardware manufacturers expecting?
