I can tell you what I have :wink: .
I love my Sena Case. I ordered it directly from Sena. Got a good deal since it was at the pre order stage.
Check out
aximcases for (obviously) cases.
WriteShield from
Pocket PC Techs is a must have screen protector. Can't imagine what I would do without it. Worth every penny and more.
Flash Memory card is good to have. CF or SD. I have 2 Lexar SD cards. Watch for rebate deals.
WiFi card. My cradle doesn't like to sync all the time. Could've been my USB port since I have an older Dell Dimension. So I sync wirelessly all the time. Never have any problem.
I am paranoid about losing battery power. So I have a
charge-n-sync cable from Pocket Solutions.
