Anyone expecting one SKU was deluded, frankly. This is a good compromise - Ultimate is basically (well, it IS) Enterprise available at retail, that's all. A tiny percentage of users will need it, and I doubt you'll see it on most store shelves.
That leaves 2 - home premium and Professional, like XP but slightly better in that Pro has all the features of home (such as media center), which was a huge gripe with me. Home premium is
rumoured to have image-based backup as well as mobility center now too which used to be only available in the business version. The other versions are for developing markets (basic) or one cheap mid devices and very low-end notebooks (starter) than you can't purchase off the shelf anyways, hopefully they won't force Starter on most netbooks as the beta of 7 Ultimate runs just fine on my 1 gig Acer. I think starter is mean to head off really low-end netbook devices that were looking at Android or the myriad of netbook-oriented Linux OS's or ones targetted to the notebooks for developing nations.
One item that I'd love to see on Home Premium though -
PREVIOUS VERIONS. Come on MS, it's an awesome marketing avenue as well - no other OS has anything like it at the moment, and home users could easily take advantage of it. I've posted the advertising scenarios that could be done with it before, an ad showing a busy Mom working on a letter only to have junior sneak up behind her when she gets distracted and answers the phone, starts pounding on the keyboard and overwrites her long document with a bunch of garbage - OH NOES! Ah, previous versions to the rescue - bingo.
