I would prefer an ARM-based server, but it seems far too many people want x86s... Go figure.<p>As for SSE, I was under the impression (I don't know where I read that) the Atom achieved its massive power reduction through a very aggressive simplification of the floating point hardware. Maybe the HT capabilities somewhat mitigate the lack of out-of-order execution. In my experience, floating point sucks a bit, but most other uses seem fine.<p>I am writing this on an Atom netbook while a Django app is importing a largish volume of data for a couple tests (it takes two hours to do it with a SQLite database) and Transmission downloads a torrent (need an alternate Ubuntu install disk). The browser is still responsive as long as I don't try to view videos. My worst complain with this machine is the hard disk being really slow, but considering price, size, weight and battery life, I guess I can't be too picky.
