Is cache cleaner really necessary?

[THEPRFCT1]

Anyone know how important it is to have a cache cleaner or optimization app? If so, which are the best? The reviews are all over the place...thanks!

I use it every once in awhile. It like cleaning the cache in Windows Internet Explorer. On phone that have low Ram, like the Droid 1's, Eris, Motorola Citrus, it can be a matter of life or death of the phone a these phones have about 384mb of System Ram and would benefit from the clean-out. Phones with 512 mb get full too. They need an app that deletes your Trash email folder...IMHO...I have helped people that had 1700 plus email in the trash folder, which sucks up memory.
