Very nice. I used to have a m125. Great little unit. First one with an SD card slot. I used it until it broke. I also had a Treo 650 for a couple months last year as my cell. Loved it until the screen and battery contacts broke. Battery life was crap, though that could be from the 2 batteries which were past their prime.
I also have a zire 71 on the bench which needs it's case cleaned after being spilled on. It works great without the case, but it is quite an awkward beast. It's my mom's, who previously had a Jornada 520, which I can't find the charger to.
I did bid on a vx with GPS cradle a while back. Not sure how much useful it would be, but never got it. I was thinking my next phone might be either a treo 680 or the electric blue centro on AT&T. I love the palm OS second only to the Newton OS on a handheld.
