Can't say I can see any reason to rush, but web developers who need to try Internet Explorer 7 beta 2, released yesterday, can find a helpful FAQ on the team's IE blog, with more info to come. At this stage, it's not recommended for ordinary users.
eWeek has a review that says: "The beta shows a lot of good progress, but, as we've said with almost every new IE release we've reviewed, it's still playing catch-up."
Update 1: Joe Wilcox of Jupiter Research has some comments and notes that you can have multiple home pages by assigning them to different tabs -- a useful feature he'd requested.
Update 2: Another good reason not to download it: Microsoft flooded with IE7 bug reports
