The sysadmin type people at my work don’t want to move to IE7 probably until there is an SP1 release. While I understand their reluctance, it is frustrating developing for IE6 knowing that a better corporate SOE alternative exists! A lot of the leak issues we experience now will be minimised, and the speed improvements alone are a compelling reason to upgrade.
I hope Microsoft release a SP1 release soon.. What if they never do, and we have to wait until IE8!?
However, there are other issues.. Other internal/external web applications, that the organisation relies upon, will need to work with the new version, and I don’t think we will upgrade until that can be guaranteed.
