Do you have a lot of programs running in the background? The only time my phone ran slowly, I looked at Task Manager and I had many (as in, more than 8 ) programs running all at the same time. If you don't use the XButtonClose setting (which has its own issues) you have to be careful about exiting programs now and then - completely closing them, not just hitting "OK" - or this (and any) WinMo phone will slow down. WinMo is supposed to manage memory for you, closing down programs when things get tight, but the Intrepid doesn't seem to do that very well.

If it's not that, I'd have to guess it's something you have installed or tweaked. There are a number of things I don't like about the Intrepid, but responsiveness and stability are actually not among the problem areas for me.
