G-mail is a killer email client and provider and I couldn’t live without it (actually, I think I could, but it would be hard 
). I’ve been using G-mail since one year after it’s closed Beta trial and loved it from the start, so much that I have Google Apps just so I can get G-mail for my own domain. Only one thing is really sucking at the moment, Themes. Plain old G-mail allows for crazy, funky and cool themes to be applied, while Google Apps / Hosted gets the standard theme. This has been like this for a large amount of months now, and I’m getting extremely jealous of standard G-mail.
If anyone knows a way around this (User scripts or other voodoo magic), without forwarding all my email to a standard G-mail account, please leave me a comment, because this really annoys me.
The best solution is to set up your own IMAP server. Then you can do whatever you damn well like.
I dont think running your own imap server is really necessary, or the best solution, gmail apps is a free hosted email service, and it gives you free imap access anyway
I’m not a fan of Google Apps for various reasons, which is why I run my own.
My Gmail Apps has had themes for a few months now, I think they are just doing a gradual roll out, I’ve had gmail apps almost since the day it came out so my domain was probably higher on the list, I’d say you will probably have it within the month….
TBH the themes were kind of disappointing to me, I was hoping for fully customizable css access, maybe I was asking too much
