I spent the last few days learning about the new features coming in Microsoft Exchange 2010. (They have a beta out now). Some of the cool features include built in support for archiving, and something called "mailtips," which is kind of a pop-up to stop people from doing dumb things like replying to all to a large group of people by mistake.
Microsoft is never resting in it's efforts to make us forget how sucky Window's Vista is, so they have released Windows 7 today. Run don't walk to your nearest retailer. Or on the other hand, maybe wait until other people try it and figure out what's wrong with it first. :-)
