While .wav is a "real, live" format, it's native PC and probably the least well supported on a Mac.
There are compression issues in audio when you get serious, or if you just like really good sound.
I'll use a image analogy because it's easier to visualize: If you have a high-rez TIFF scan of a picture, it's huge. You can reduce the size to maybe 1/50th or 1/100th if you reduce the size and convert it to a JPEG, but when you do you throw away a lot of information and the image will never look as good as the original.
The same sort of thing is true with audio. Your CDs are recorded at 44.1KHz, 16-bit and use about 10MB per minute of play. Most NLEs like 48KHz/16-bit. When you converted to an MP3 or .wav, you are throwing away maybe half to 3/4 of the audio info, so when you "up-rez" to 48/16, you have very little to work with in general, and fixing anything gets difficult. Even going back to 44.1/16 will show you a lot of loss.
If they're just "tunes" to you and play OK on whatever you listen to them on, then MP3 (or .wav) is OK but now you understand what you're risking. I keep all "important" at the highest quality it was available to me in, so that when it gets compressed (which it almost always will) I'm working from the best quality source.
As you probably know, the AIFF files are about 10X the size of MP3, AAC, m4a, etc. It's the price of doing things the best way possible. Whether it's practical for you is something for you to decide.
