I've always enabled it through some third-party app on all of my PPCs. Part of it is that I don't like seeing that little free memory. Mostly, I just don't trust the WM memory management to free up memory as needed. I use SPB Pocket Plus and watch that free memory counter drop as I use my device so I know I have memory leaks somewhere. I wonder how many of those would be eliminated/reduced if MS actually built-in Close functionality so that programs could terminate cleanly?
Maybe WM does do a better job managing memory, but I still should have an easier way to determine what programs I want open/running at any given time. This has been an issue for as long as I've followed/used the PPC/WM OS. People have kept asking for it and MS will not deliver. I agree with the poster earlier that the argument they present is one of the worst I've ever seen.
Now for the more important question - how can I get AKU 3.x for my HTC Wizard?
