I work off of a MacBook Pro. As much as it is a portable, I hate to take such an expensive computer on vacations just for email/surfing and having work files with me (just in case). It is nice to have it for viewing photos taken/backing up.... but what about buying a used 12" iBook? G4s can be had pretty cheaply. Would a G4 iBook run CS3 for light work? How are the LCD's compared to more recent portables? Do most have 802.11g cards or 802.11b? Perhaps going back 3-5 yrs is only asking for problems in another 2-3, but considering it as an option.
