SL - same if installed originally vs. upgraded?

    Assume this: Snow Leopard (SL) is going to come out in summer.

    Now, if you get a MBP now with Leopard and upgrade with SL later, is the result going to be the same?

    In other words: Based on previous upgrades (Tiger -> Leopard), is the new OS able to totally overwrite the old one, thus eliminating all 32 bit code?

    Yes, of course. Just do an Erase and Install. Or format your hard disk first, after backing up your files.

    BTW Snow Leopard will not be totally 64bit.

    Really? I thought SL would be the first 100% 64-bit OS

    I plan on buying and installing Snow Leopard a couple months after its released. This way some of the initial bugs should be fixed.
