Storage shouldn't be as much of a problem as Program memory. Afterall, you can install most software right onto an SD Card if you're feeling storage-constrained. The only software that tends not to like being installed on an SD Cards are those utils that need to launch on startup. Heck, I think I had over 1.3GB of installed apps on my Storage Card up until a few months ago.
Program memory is a problem though. There isn't any way to increase your program memory unless you just stop running some things. Sure wish I had 96MB or 128MB of RAM instead of this piddly 64MB (of which I only seem to actually get 47MB, and 27MB of that is already consumed by WM6 and the handful of things I cooked into my ROM).
