My Vaio laptop stays up for weeks without reboot. Sometimes it does hibernate. The issue of not coming out of Hibernation is ussually a win 2k/xp problem. There is a fix for it out there (Sorry I dont have time to find it for you at the moment, if you need it let me know and I will find it). As far as the wireless connection going out, that happens alot, esspecially if there is some sort of interference.It can be fixed without a reboot. Run ipconfig/release and then ipconfig/renew at the command prompt, or go to the wireless network manager to reconnect. Macs utilize memory better than windows, so they dont need to reboot as often.
