Well, if you haven't already started using SQL 2008 then it's about time!
Microsoft yesterday announced the RTM of SQL 2008. You can get all the information about it HERE! You can also install a trial version of it from HERE! While you are there be sure to check out the Overview Demo of SQL 2008. It very elegantly explains the why/what of SQL 2008.
If you attended the launch events don't forget to use your coupon to redeem a free version of SQL 2008.
