What I realised I found annoying was that when I opened Hotmail it was the "other" that appeared first. Shouldn't it be "focused" which one would assume are the important ones?
Gmail's lke that, Mamya: three different choices - primary, social (FB notifications etc) and promotional, from newssletters etc you've signed up to. Junk still remains separate there too.
I'm quite happy getting my Gmails sorted like this as there are so many of them. I get fewer Hotmails, so I don't mind seeing them all at once.
