You know the pleasure you get when you add a colorful new theme to your iGoogle page? OK, multiply that by 1,000, and I give you the sleek new themes for Gmail. Just launched today, there are already 30 different themes to choose from — ranging from nature themes to shiny and chrome-style themes. Google has given Gmail a little makeover with crisper and cleaner lines (it reminds me of Google reader). To spice up your email, go to the themes section in settings and you should see the new themes. And if you don't see them, keep checking back and they should appear sometime within the next few days!
