I purchased the clip+ because I was beginning to run out of space on my 2Gb clip. I purchased the 8 Gb Sansa Clip+ and have really enjoyed the extra space. The only real difference is the ability to use expansion cards, which I haven't used yet. If you are running out of room then the clip+ is an inexpensive and very functional route to go. Just know that you don't gain much other than more storage space.
