Hooked up my my Surface RT to use as a desktop PC, and it worked ok. Although that had 2GB or RAM, also has video out, and office which doesn't require a subscription. But this HP one doesn't have the crippled RT operating system.
Yeah, don't get me wrong, a tablet can work well as a netbook/laptop, or desktop if its the right kind of hardware. Or at least okay. Particularly with the newer m-core models coming out.
But it really does need I think, native video out - and I have found some 1 GB devices painfully slow at times. As it is, a tablet will run slower than a full desktop, laptop, one really doesn't want to make that gap larger (as an example, my two year old, then second hand HP desktop, with 6gb of ram and and SSD upgrade is still a lot quicker than a new high end tablet which would cost more than it did two years agp).
At the same time, a cheaper windows tablet, or USB computer, can be a pretty darn good entry level machine on a budget, especially if one doesn't know how to assemble ones own desktop. You might even be able to tolerate 1 GB ram (I wouldn't) but you really must have a video output.
And adding a video output here, would cost more than getting a tablet that has an HDMI, and more ram, and also more than a USB stick computer, with more RAM. So cost effective wise, and speed wise, for a PC, this model is not the best idea IMO.
