Now they would really price it high because of the trackpad
I really just want a backlit keyboard. Since most of the time while I am on the comp its dark.
Turn on the light?
I can see why in laptops a backlit keyboard can be important, since you don't always have control over the environment you are in while using it. On a desktop, if its too dark, you are presumably in your own home, so turn on the light!
If there's people sleeping next to you, then probably they would be annoyed at the tapping sound of a keyboard anyway. And if they're tough sleepers, then they wouldn't notice the light anyway (even a little light would help).
For movie watching, the Apple remote has everything you need to control that task.
And they do have custom key caps (well mats you put on over the keys anyway, which you can type on, helps protect your keyboard while giving you the extra feature at the same time) you can slap on Apple keyboards for short cuts and such for the professional programs like Photoshop, Logic, Final Cut etc.
