Full x86 gaming rig tablet for $500 - $600. You can get the atom based tablets with Win8 Pro in that neighborhood, but start putting in Core i5, more RAM, etc. and you are pushing close to $1000 or more. What kind of gaming laptop can you get for $500?
Lol, try to be more creative
Think smaller. A decent Pentium or i3 is more than enough for the CPU. Even a Celeron with a decent frequency would do the trick. Graphics doesn't need to be anything special. If we think about Haswell, GT3 will probably do the trick. If not, then a weak little graphics card of some sort with performance comparable to, say, a Radeon 6670, maybe a little better, will be plenty. 4GB or 6GB of RAM is not a lot and is very feasible even if it's shared between the graphics and CPU.
Throw in an SSD around 120/128GB or 180/196GB or even 240GB/250GB/256GB or an SSD-cached low RPM 250GB to 500GB hard drive and you're set to go. The hard drive could even be a very thin and cheap to manufacture single platter model at such capacities.
You most certainly don't even need Windows 8 Pro as was earlier suggested. An OEM copy of the non-Pro x86 version would do the job just fine. Heck, maybe there's a Win 8 x86 starter edition that I've forgotten about that would be fine.
