NOPE. Doesn't work here. I tried it.
I've been using Mac since 1986 and the one difference I found on the Mac vs. PC battlefield was that, despite step-saving conveniences, Mac never assumed settings and actions you didn't ask for.
Certain things need changing, this wasn't one of them. Most people don't want their previous sessions restored automatically unless they somehow didn't finish when they shut down or they crashed. When you quit, there's supposede to be an option for it, that's all.
Otherwise, it should be "new startup, new session." Simple convenience...not inflexible, PC-type assumptions you need workarounds for to achieve simplicity.
Don't get me started with the stupid changes they made to Lion's version of Preview, with no more "save as..." and other things we didn't ask for.
