Themes are nice, but... From what I've read, Exchange 2007 was supposed to provide a 'better experience' than Exchange 2003 for non-Windows access, using non-Microsoft browsers. Unfortunately, 'pretty' seems to have been given much higher priority than functionality. The OWA 'Light' client, for example, can't print. What good is an email and calendar client that can't print? There was functionality in the OWA2003 product that is now gone: the weekly calendar view, for example. Apparently the idea was to make a pretty, static, page that doesn't use frames so it can look nice on browsers more than 5 years old from niche browser vendors. A company that was really interested in cross-platform support would have noticed that the major cross-platform web browsers (e.g., Firefox, Opera) all use frames, all are more web-standards compliant than IE6, all support subsidiary windows and tabs. Judging by behavior instead or talk, I have to conclude that Microsoft wants to sell Exchange 2007 only into all-Microsoft shops, because they sure as h*** don't want to work with other desktops.
