This Krusell Multidapt case is outstanding. I've owned three of them now. I had one for my Treo 600 and bought another when I upgraded to the 650 - which was destroyed by my dog and now I have my third. I have used a variety of cases for the Treo and, to me, this case is the best. It is very low profile, which is important to me. I use the Spring Clip because it is also very low profile but easy to get on and off a belt. I also have used the Big Clip and the Mini Clip. Both are heavy duty but clip on so tightly that they are a little difficult to install and remove from a belt. The Swivel Slip is a standard swiviel clip and is in no way low profile. The Spring Clip has enough play that it will swivel a little bit on your belt and slide back and forth pretty easily. There are two models of this case available - only one from Amazon. One has the screen compeletly covered and the other has the screen cut out of the plastic. I started with the full coverage case hoping for maximum protection, but quickly realized what a pain it is trying to use the stylus through the plastic. I used a razor balde to cut out the plastic over the screen and it was great after that (I do use a screen protector on the actual display though). TreoCentral carries both and hopefully Amazon will too soon. The factory cut job on the plastic is much better than my attempt. That's the way I would recommend going. I don't think you can go wrong with the case. It is very convenient to use. Some people are concerned with the display facing out, but I've never had a problem with that. I'm not gentle with it and mine has never gotten damaged.
