I got my brother in law an Acer netbook for christmas running windows 8 specifically for this purpose. He's running RomRaider and Ecuflash with no issues whatsoever. The computer has awesome specs too! 320 gb HDD, 4 gb ram, processor is a little puny at dual core 1.8 ghz processors. Overall if a million times better then waiting around for the right tablet and a quarter of the price (was about $300 new).
p.s.- windows 8 is pretty sick
