The AMD vs. Intel battle is an old one, as old as nVidia vs ATi. It’s a tug-o-war, one leads the other follows, then they switch positions and the other leads while the previous follows. Remember Voodoo? TNT2 baby.
A couple of months ago, ATi was the way to go. Now it seems to be nVidia.
Centrino is good for battery life, but Celeron M is getting rave reviews. I myself am I Celeron M believer - it’s the little CPU that could.
AMD offers better bus speeds, but right now Intel offers higher CPU/RAM speeds. Yes, it comes at a price premium… but so did DDR when it first came out.
When you have competition in a fierce market like this, the turnover is really high, and the introductory prices are a joke. But it’s the price you pay to be at the forefront of the technology revolution.
Right now, AMD/nVidia is the way to go. Few months from now… who knows?
