Really? Seems the opposite of my experience, getting 40-50% smaller files with equal or better fidelity with the original. AAC employs a much better psychoaccoustic model than MP3, which is how it gets better results with fewer bits.
Now if Apple could come up with a lossless codec to use instead. And I know I don't like the part about not being able to put downloaded music on more than one computer... in order to prevent putting a backup on an external HD and then hooking that up to another computer, it'll have to be tied to the HD and iPod. Which means, unless you have an iPod, you can't back up the music at all, meaning that the next virus, magnet, or sudo rm / -r turns your music into so much wasted cash. I do like the idea of free songs, or discounts, to .Mac members though.
AAC (and WMP, for that matter) DRM does not keep you from copying files. It keeps you from using files branded to one computer on another computer. Usually (but not always), you can "back up" your computer's identifying key as well as the files themselves, in which case when you buy a new computer you can move all your files and your ID key over to the new computer and everyone's happy. Of course, this isn't perfect DRM (there is no such thing!), as there's nothing keeping you from just putting the same ID key on multiple computers, but it makes "casual copying" less convenient, which is about all DRM can really hope for in the first place.
Personally, I don't think the music companies should be too worried about people burning their songs to CD, etc. Yes, one can then rip the CD back out to high-bitrate MP3s, but you definitely lose quality with each burn/rip decode/encode cycle. IMHO, the CD is a convenient format, but not necessarily my archive format. I'd love to be getting better-than-CD audio via download, archiving these tunes in digital form, and burning to CD-quality for use in my car.
