You would rather open a hulking application like iTunes+iPhoto rather than just iPhoto? Use some logic please.
Why don't you use Logic? I already use it (the Logic 9.1 Pro that is).
Seriously, have you used iPhoto? Have you used iTunes? iPhoto is 10x more bloated than iTunes could ever hope to be and that's be conservative. 1000x wouldn't be out-of-line. iPhoto SUCKS. And it's not free unlike iTunes so it'd still make a lot more sense to have a basic picture and slideshow viewer in iTunes than none at all.
Something light-weight like Xee runs circles around iPhoto for just viewing photos quickly and easily and THAT is the performance we'd be talking about, not replacing iPhoto with a build-in viewer. iPhoto is more for organizing photos and albums than viewing them and iTunes could easily import albums as playlists (already does for AppleTV and iOS devices) so why no options to view your existing photo library?
Furthermore, iTunes is running here 24/7 while I almost never run iPhoto so which would be easier for me to drop into to view some photos quickly? As it is, the best way is to use the Finder to view the thumbnails and the spacebar to preview. Trying to use iPhoto to view a picture quickly and easily is like trying to use a sledgehammer to hang a picture frame, especially if they're new photos. As I said before, you could go eat dinner in the time it takes iPhoto to import 500-1000 vacation photos. Xee will bring them up instantly. iTunes could let you make playlists of photos quickly and easily, just tag and forget.
You seem to think it makes more sense to run two products for media when one will do. Why not have a separate tv, separate movie, separate book, separate podcast and separate radio and separate music program to view/watch/listen to that media instead of putting them all in iTunes? And yet you have the NERVE to claim I'm the one with the logic problem?
Call it what you want. But to me, and every sane person here, it sounds a whole lot like bitching.
You whine about bitching, yet you imply people who do not agree with your point-of-view are not sane.
I might as well call all the endless gushing nonsense from the fanboys on here a bunch of groupies hoping Mr. Jobs will ask them to come back to his dressing room. But the truth is that there are always TWO SIDES to every story and if you cannot handle people giving their opinions on a message forum without insulting them, you should be spending your time elsewhere.
