It has its flaws, but I find myself again and again returning to GMail's web client after trying out desktop clients.<p>I have tried:
* Thunderbird
* Claws
* Mutt
* Pine
* Others that I can't remember.<p>The question I have is: why, given the limitations of the browser, is GMail still better?
Thunderbird has excellent support for encryption with its "Enigmail" plugin. It's the most secure and seamless encryption I can imagine. For example, it has options like "always encrypt when replying to an encrypted message", and "always verify before sending".<p>I suppose with Gmail I could use GPG via copy and paste, or perhaps the now abandoned "FireGPG" plugin for Firefox. Anyone else here use encryption?
Gmail is the first email client that allowed me to focus on communication and not worry about how to catalog stuff, in order to find it later.<p>The concept of archive, fast search and threading are something I wouldn't want to be without anymore.
Surely the question should be: why aren't any of these desktop clients good enough for you to stick with? What are their flaws that outweigh those of Gmail?
