have been using the e-mail app that comes with droid now for a little more than a week. i am a corporate user so i use EAS and i am coming from a windows based device. it seems to work ok and i dont have any major complaints but i noticed there are some things it doesnt do, so i will be looking for other apps and evaluating them.
right now the three top annoyances **for me** with the droid mail client are
1. it doesnt display .eml attachments. well if your dorky co-workers have iphones and forward you messages all day from said device then you end up with a bunch of unreadable attachments on your droid.
2. html e-mails dont display well.
3. folder sync is sporadic or not working. a refresh of the folder will download messages but it doesnt work well on its own.
i would love to hear other gripes - but keep them brief - and if other mail clients have issues lets hear about them!
