Yonah is definitely here and at bellow $750.
Compaq V5000T 1.66 Duo 15.1' 40GB DVD/CDRW $675 after ($250 in rebates) might or might not have IEEE on the Left side - check. For that matter
HP dv1000t 1.83 Duo 14' 80GB $895 after ($150 rebate and free upgrades) or $999 with 2.0 GHz Duo but the same Intel PRO/wireless 3945ABG and similar no Giggy or remote which is useless but cost $15 extra. Compaq configured the same as HP would come to $890, but HP has more options and rebate is only $150 vs $250.
It is +$125 to go from 1.66 to 1.83MHz and +$150 to go to either 2.0 or 2.16 on Compaqs but only +$50 and +$75 on HPs and overall HPs are more solid and have more options, alas 14" screen. So where does it leave Apple with Mini 1.66G Duo 512M 60G Superdrive at $799 or MacBook with 1.83G Duo 13.1" 512M 60G no Superdrive at $1099 or MacBook with 2.0G Duo 13.1" 512M 60G plus Superdrive at $1299 ($200 for 2.0G and superdrive) (black is not worth it for $200 extra is for going from 60G to 80G - $200)? Clearly, without $100 rebate on Mini they are no longer interesting and become obsolete in less then 1/2 year. As for Notebooks HP and the rest are beating Apple on price too by $200-$300 or 20%-50%. So the only reason to buy Apple is still software and the only piece of Software that I am missing is FinalCut Pro, but it is not inclunded (only iLife'06 is), so... test how good iMovie and new FinalCut is and give up on Apple hardware.
Anyhow when buying new notebook look for FireWire and hopefuly non Intel PRO/wireless (doesn't work with OSX86)... Otherwise, do not understand why OSX86 didn't install on Toshiba - try 10.4.3. On D600, do not upgrade from 10.4.5 and do not expect more then what is working already - simply try iMovie and FinalCut Pro - give Apple another chance, but without either one of those there would be no reason to run OSX86 apart from coolness factor and pay for overpriced hardware
When buying Desktop... Is it really worth spending $300 on yonah desktop when yonah notebooks rapidly approaching $600 mark? Anyhow, when buying Desktop for parts to build Media Center System look for 800MHz bus (667MHz the very least as on Apple), non-LGA775 socket, double layer DVDRW and FireWire. Most $300 Desktops are LGA775 (all Pentium 4 HT and Celerons numbers not ending on 0).
