In a hurry to catch my connection, I left my SL100 on the plane and I'm not likely to get it back. So, I already have two home docks and a car dock. I've read breifly that they can be modified to accommodate a SL2. The question is, other than the size and the SD card, is it really worth getting a SL2 or would I be better off trying to find another SL100? I never had any problems with my SL100 and would hate to upgrade if the benefites aren't worth the cost or if there are inherent problems with the SL2 that I'm not aware of. Thanks in advance.
