I have 4 email accounts that I use with the stock email app: Exchange, Hotmail, Yahoo and Gmail. I have found that the email app is painfully sluggish. Here is a list of problems: Application is slow to load email Keystrokes take a long time to register in this app - which is VERY weird. Weird and very frustrating. Navigation within the app is very slow I have reinstalled the app twice already by the problems do not go away.
