I’d go with Bigger Attachments. Try sending a 15MB flash movie through an email and you’ll automatically know whether unlimited storage really makes much of a difference when the email file size limits are so small. With Gmail I can send such huge files now(I could always receive them), but if the recipient is a user of Yahoo! Mail the mail gets rejected.

I’m sure Yahoo will be making a move to challenge this increase in allowable attachment size that Gmail has introduced in their latest interface but until then I’ll have to trust xabhishek.com rather than Gmail if a poor Y! user wants a huge file from me. 20 MB may look very big for some people and maybe also unnecessary but I would like to point out that many services abroad accept photographs which need to be printed by email rather than a regular upload. Saves them a whole lot of script load on their server. And if I cant send even ten 6-megapixel shots by email, think of how small 20MB is.
