Well, I have to advertise my own E-Wallet solution, which does not (at least currently) offer much security, but focuses on ease of use and anonymity & privacy:
https://easywallet.orgCurrent feature improvements I have in mind (priority list):
1. Email & SMS Notifications on balance changes
2. Send bitcoins via email
3. Possibility for passwords
4. better mobile interface
Any other feature requests/comments welcome.
