I bought a Droid X when the X2 was about to be released. After about 6 months the phone slowed to a crawl. I reformatted it many times over several weeks as the Verizon sales person suggested and even was given another X. The phone was still slow. I have a windows phone now and am already bored with it. My question is this: does android still do this? Does it still slow after a while? Also does task killer work? I remember people telling me task killer is a must have and others told me it messes up the phone.
