Yes? You don't hit the newspapers frequently. Apple is already _selling_ 90 nm versions of it's 2 Ghz G5 chips in the new Xserve G5. http://a192.g.akamai.net/7/192/51/0c5b0d0ef0f03b/www.apple.com/server/pdfs/L301323A_XserveG5_TO.pdf A 2.5 Ghz version of this chips was already presented by IBM and 2.5 Ghz PowerMacs are just some weeks away. regards Andy
