I recently ordered a Levono x120e ($397 from B&H) to replace my aged HP nc2400. I got the unit with the AMD Fusion E-240 CPU and ordered an extra 2Gb memory (total 4Gb). Which Fedora should I load on it? 32 or 64 bit? They do market Win7 64 bit for it (I just ordered it with the basic Win7 personal as I am blowing that away anyway for Fedora).
