I use them a few times then uninstall them. The only ones I keep are chomp and taskkiller. Everything else I use a couple of times then never use them again. Not until weeks or months later do I re-install them only to un-install them again. I've already reset my phone 3 times. Reason being, even if you uninstall the app some stuff still remains. Phone starts to get slow after a while. I think I'm just addicted to downloading apps.
