In Brief: iBooks can currently only mirror the desktop on a larger screen, not extend their desktop. The logic behind this being that it should be a feature reserved for the 'professional' laptops. Do you think the MacBooks will also have this limitation? Background Info: After using a 12'' iBook screen for two and a half years, I think I'm starting to really crave some more screen real estate. Now, I have about £1400 ($2000) to spend on a new system, and I need a portable. I'd love to be able to buy a 20'' display to go with it, but I can only afford that if I get a MacBook, and in any case.. the MacBook would have to be able to drive the display at its native resolution, otherwise what would be the point? As an aside, do you think the MacBook Pro's screen is big enough for everyday use? I can't really see how the increase in screen resolution would be big enough to be useful. If you have a MBP, can you have a Word window and a Safari window both visible at the same time and still be large enough to be usuable? In another thread, somebody mentioned that they thought the limitation would be removed, as the iMac also used to be limited to display spanning but now, with the intel iMacs, isn't. Thoughts, opinions and two cents are very much appreciated! (P.S. I know there's software available to 'correct' the limitation on the iBook, but there's no guarantee someone will be able to do the same for the MacBook, and I wouldn't like to make a purchase on the assumption that someone would).
