Well, I don't want one. :-) I have some serious problems with gmail Terms of Use.
Google reserves the right at all times to remove or refuse to distribute any content on the Service...
Google also reserves the right to access, read, preserve, and disclose any information as it reasonably believes is necessary...
you agree and understand that Google will display ads and other information adjacent to and related to the content of your email
You agree to hold harmless and indemnify Google, and its subsidiaries, affiliates, officers, agents, and employees from and against any third party claim arising from or in any way related to your use of the Service, including any liability or expense arising from all claims, losses, damages (actual and consequential), suits, judgments, litigation costs and attorneys' fees, of every kind and nature.
[EDIT]reworded & added some of the slightly scary terms[/EDIT]
