You know that software-only view will hit a very hard wall... :)
you can get dual-core atom in a desktop model, and I thought I've
heard of people dropping those chips into netbooks... or maybe just
wishing they could.

Sure, hyperthreading is generally better than not, but of course it is
a hack and using hyperthreading on a dual core is much better.  A
single-core hyperthreading-capable processor still has one cpu core.

I don't believe that a hyperthreaded CPU has more available horsepower
than a non-..., but rather that is a hack to better-handle the
software, which hasn't kept up (or been able to, no blame).

cheerio & tgif,

Ben
