I've been using various macbooks for well over 3 years, and really am sick of each OS update presenting a 50% chance of the wifi connection being ruined. I mean if you google macbook wifi problems, you will see people experiencing problems for almost every single consecutive OS update. I don't know if its a OS problem, or just shoddy hardware, but really it sucks especially how great macbooks are in general. I mean the main reason for me to have a laptop is the ability to be online anywhere, but I'll probably just get a iMac instead nextime around. I'm glad Windows 7 is out soon and is a good OS from MS for once, because I will be able to have a backup OS for the almost inevitable wifi dropouts I might face in the future.
