I am aware of some threads like this one, but I haven't seen a problem this severe addressed. I regularly use a task killer to manage my memory usage. I know that programs are loaded in memory, and android will close programs to make room for larger ones. BUT, I went about 2-3 days without managing my programs. After coming out of school my phone was so incredibly laggy I couldn't unlock it. The slider would laggily (I doubt that's a word) follow my finger and then snap back to its locked position. I hard to restart my phone to make it usable. I'm 99% sure this isn't normal. Any suggestions? BTW, I'm NOT rooted.
