Of course, the only reason you're using Adobe's servers is that Adobe chose to roll their own cloud service instead of using iCloud like everybody else.
What a daft thing to say.
A: Adobe would be insane to rely on Apple given they have a history of dumping things [Aperture being just the latest] without informing or caring about others. The Cocoa/Carbon fiasco being a good example of where companies got screwed over by Apple.
B: How on earth would that be of any use to the millions who use PCs?
C: 'like everyone else' Such as?
But when you factor in competing apps like Pixelmator that give you 99% of the commonly used functionality in Photoshop, and almost full file format compatibility, all for the cost of a couple months' subscription to Photoshop CC, that $120 annual fee starts to look like highway robbery.
PS is a pro standard programme and Pixelmator certainly does not even come close to PS's capabilities. Not to mention that the vast majority of PS users are not photographers.
Besides if you are not a pro why not buy PS Elements
Photoshop only commands the price they do because they have a monopoly among large prepress houses and similar. Everybody uses the same tools so that they can read each other's files.
Loads of software can read or open Adobe's files. They even introduced an open source raw file format that anyone can use for cameras to stop the idiocy of not being able to use a new camera's raw files due to a model number change. You seem to be confusing Adobe with Apple who certainly like to trap you into their software with their propriety file systems and ways of working.
For everybody who isn't doing commercial work, you'd have to be crazy to stick with Adobe products. Their products are, for the most part, massively overpriced for what you get.
So professional tools are overkill for non professionals - only accurate thing you have said.

I would switch from iPhoto to lightroom but I have no way that I know of to move ratings from iPhoto to Lightroom and I have about 20,000 photos rated. Any recommendations?
Apple are working on a migration tool for Aperture to LR. Ironic really. It should do the same job for iPhoto libraries and information.
