My top two gadgets from Wired's top ten gadgets of CES

I don’t see how the PC “case” will work. Every time I try to upgrade I find that so many things have changed. My new GPU needs a new bus to get full speed. My new CPU needs a new type motherboard with a newer type of memory. Sure I can re-use the hard drives, maybe. But by the time I upgrade my PC I usually need more than double the space and it’s much nicer to swap in 1 or 2 double size drives than have the 2 old ones + 1 new one, etc…
