So I was browsing XLR8YourMac's website when i saw the Powerlogix press release concerning their Pismo upgrades. They are now avaliable in 900MHz G3 upgrades. Seems like a pretty decent upgrade for $349. I love my little Pismo, im not a metal freak and never was too interested in the titaniums (until that 17", that is...) Even with just a 900MHz upgrade, in a couple ways it still kicks the ibook's butt.... 1GB ram capabilty, superdrive upgradable, dual battery capabilty... But anyway, I was thinking.... why are there no faster upgrades for the pismo in G4 than 500MHz? Does this have to do with the more specific power requirements (core voltage, etc) for newer G4s like the 7455 or whatever it is they are using in the titanium laptops? What Im basically wondering about, is it likely at all that an upgrade company will be able to develop a faster G4 upgrade for Pismo and other laptops like Wallstreet? I can't see any reason why there couldn't be say a 667 upgrade for the Wallstreets (66mhz bus on a 10x multiple) or an 800 or 867 or even faster for the Pismos, thanks to their 100MHz bus. Sure it might be expensive but a 867 or 1GHz upgrade for my pismo is much more appealing (and even if it was expensive, im sure it would be less than one of the new g4 laptops...) A G4 upgrade would be much more ideal for me, because I do a lot of audio work on my pismo, with altivec enabled stuff like Absynth and Digital Performer. Just wondering what everyone's thoughts are, and if there are others out there like me wanting more G4 power for their Pismo.
