But I will say my experience is that once your iPhoto library reaches a certain size (for me, as I remember, it was about 1000 photos, but it may depend on the size of the files created by your camera) you should always be taking regular backups of it, as bad things can happen.
thanks for reminding me to back them up!
i've heard iPhoto horror stories too.
oh yeah, in wales, keep 10G empty on your hard drive, and repair permissions every week or so.(in Disc Utility, in the Applications folder, in the Utilities folder), especially if you have downloaded anything from the net.
OS X needs 10G of free space to operate correctly. The person who says it cannot be done should not interrupt the person doing it. Chinese Proverb.
On a related note, I refuse to Mac computers, stemming from my basic and complete incompatibility with the Mac interface, a problem I've had since childhood, before Windows had been invented.
I switched from WMP to iTunes a few years ago due to the horrible shuffle system on WMP. When you'd skip a song, it would always go right back to that song after it finished the one you skipped, so I was constantly drug back to a song I didn't want to listen to at that moment. iTunes does not have that problem. All of my music is off CD's and such non-protected sources, so I've really not had the problems that some have reported. I was aware of its drawbacks before I started using it, and have been keen to avoid them.
