I use Mail.app for mac. I have an IMAP account that has squirrel mail access and essentially infinite storage. The squirrel mail was a pain and I went to gmail while I was in the corporate world. Now that I have a startup I am mostly on my machine and the webmail is just a backup that I seldom use if I'm on another machine. -I like drag and drop attachments. -I like the OS integration. Click on an email link from the browser, send something from iPhoto etc... -I hate that when I hit tab on gmail it focuses on the send button. -I like having email offline. -I like to be able to fast-seach AND THEN sort. -I like realtime spellcheck. Gmail is the best web interface by far but in my opinion it is inferior to mail.app. I think the tipping point comes when you're spending more time on a machine w/o your client, gmail is the way to go.
