Hi Mac Friends: First at all, please excuse my English. I have a Rev C PowerBook. It Was having some problems as Warping so I send it to Tech Support. They scracth my case and didn´t solve the problem so they are reoplacing my PB. The problem is that I am getting a fully new PB, and I am thinking to sell it without oppening the box. Just as new. That is because I don´t know wath is gonna to happen in the next weeks. It is going to be a new PB? It is going to be a full new redising of the actuac PB with liquid cooler and some more speed and better Graphic Carp? Are they going to come up wth the double core? Maybe some better display and faster G4 prosesor? Maibe the G5? I don´t know wath to do. It is a lot of money in Argetina and I don´t want to open the replacement and finding the next thay that Apple come with a new one. But maibe I just have to enjoy my PB that i could´t before because of those problems. Wath do you think? Thanks, ARIEL.
