MichaelCrawford: As I understand it, Centrino is the marketing name for the combination of a Pentium-M and a certain Intel northbridge/southbridge and Intel's 802.11b wireless chipset. The Pentium-M is an update to the Pentium 3 (well, Pentium Pro or 686 to be pedantic) to include a bunch of new features, including better powersaving features, SSE2, 400MHz front-side bus, a large (1 MB) L2 cache etc. The MHz difference is to do with the fact that the P4 has absurdly high clockspeeds to achieve its performance (the NetBurst architecture), which also explains AMD's Athlon performance ratings (eg 2500+, 3200+). Just as a 1.4GHz P4 was outperformed by a 1GHz P3, a 1.6GHz Pentium-M is equivalent to a 2.4GHz Pentium 4M. I don't know anything specifically about Athlon notebooks, but I suspect you could compare on MHz vs P-M, and +rating vs P-4M. There was a bunch of stuff about ibooks here, but you specifically say "Windoze", so I've deleted it. There are some compelling points for iBooks (including price and service - Apple will happily service laptops bought anywhere worldwide).
elixxir has discovered he can be logged in as me when we are both using the same (UWA) proxy. I'm not entirely sure who's fault it is, but I'll blame k, since not only is he a squid developer, he works for UWA and I know where he lives. elixxir and I are still trying to nail down the problem, but currently if I log in, he can then see /acct and /diary as me, and if I log out, I can go back and see these pages as though I were still logged in. I also briefly saw his /acct page while we were testing, but logged out (as trs80?!) before I realised this. Speaking of which, how did nospamplease post an article while only an Observer?
