I've had my fully loaded (2 Gig Ram, 5400, 128) Rev. C for a couple of weeks now and it's causing me problems. My Rev. A had a perfect screen and no issues. My C arrived with a loose key, has just developed a stuck pixel and, most annoyingly, keeps losing touch with my wireless base-station, requiring me to reboot to get my connection back. I'm running Panther with all the latest updates and have been having this problem since before the last bug fix (yesterdays). Also Mail asks me for my email passwords every few minutes despite them being entered correctly in my account details. Sometimes they're not accepted at all. I always click the 'remember this password in Keychain' option but it seems to have no effect. Any suggestions (particularly for the Mail problem) before I send this thing back. My GF's 15" arrived dead from Apple and I'm beginning to wonder if there aren't problems with PB's...?
