dunno is y'all knew this or not, but I was frustrated by the lack of a "bookmarks" function in iTunes Music Store. What if I wanted to buy something later and I couldn't easily remember what it was? no problem-o! just click and drag the album cover from the iTMS to the desktop. Bam. It turns into a standard URL file that when you double click it, comes right back to what you were looking at. This works for anything that acts as a link in the iTMS, whether it's a song, an artist or whatever. Nice, huh?
[robg adds: This is most dangerous for my wallet; in the past, simple memory failure meant that I'd often forget what I'd wanted to purchase a few days ago...]
