Has anyone here even tried SmallMenuPlus? It gives you the feel of real windows on your Treo. It can be used with the Start Key on the device, and if you make folders in Explorer it can even look exactly like Windows with Start, Programs, Etc.... Give it a look if you've never used it, they have a trial period. I've been using it for 4 months not a hitch, works perfectly.
