Used to have a MAP Subscription but have switched to TechNet/MSDN with the download option. The marketing fluff is just that, a few nice glossy folders to show customers and DVD's of how to find the right M$ solution for your circumstances. The beta software (and info) is far better from TechNet the licence agreements vary slightly - I have some TechNet disks with full licences while MAPS is soley NFD.
EDIT:Also MAPS now has its annoying subscription renewal "test" (to stop customers simply getting all their software for "free") which is an additional PITA - even though you can easily score 70% without looking at the marketing manual.
Also if you cancel MAPS remember you are required to destroy all your media and CD-Keys
