Hello folks. Just wanted to stop in a say hello. Im a frequent lurker and Ive decided to join the fun. Currently, I have a dual boot Dell Inspiron 5000(XP, Redhat 8). I do most day to day type activities in xp and development efforts on the linux side. Quite frankly, rebooting all the time is a freggin pain. Ive been considering getting a new Powerbook. At the moment with all the grief about ship dates for the PB17, my purchasing will not take place until the desired machine is in stock. From a consumer standpoint, I think it is absurd that Apple "released" the 17 and is holding everyone off for months likely. From a corporate standpoint its somewhat brilliant. Mac fans around the world are awaiting these like children await santa on christmas eve. Its like the > 3K price tag is not important. Anyway, to my real question. If I were to make the plunge, what kind of performance differences would I expect in the 15Ti vs the 17. Im of the opinnion that a new 15 will be released and Im just wondering if its worth waiting for. The current 15 could be had a quite a discount if another 15 appears in the near future. Anyway, just curious what your opinions are. Thanks for reading my long post.
