If you really think it is value, then buy it. Are you writing on a Windows PC? I am writing on a Mac, at least I actually went out and bought one (and I really like it, btw).
Dell's (and other PC notebooks) have mult-touch (see other post), unibody is useless (oh it looks pretty), Magsafe? lol... wth.
Can't afford it? See what I am saying? There is no reason you shouldn't be able to afford it - Apple should be somewhat affordable, not the outrageous prices Apple makes you pay. If you are tired of Windows, switch to Linux.
