Hi All, Lately I have been considering an issue and couldnt quite come to the right answer. is it true that certain programs cant be installed on flash memory? I have been looking at the 15" i7 but i hear that there might be an upgrade due around 2011, does anyone know anythng about this and what it is likely to include? Reason is i would not like to spend the money on the 15" only to find that a later greater upgrade is avail. in your opinion, is the upgrade likely as soon as april-may next year and is there likely to be any significant improvements? MB Air has been touted as the "next generation of macbooks" so i was thinking that MBP might have something along the lines of flash memory and thinner design..what are your thought?
