I think if I could go home, and have my bookmarks be the same on my home machine as my work machine, that would be awesome. One of those things you could get extra value out of .Mac to make it worth the $100 they're going to charge us next year.
It seems to fit in with what they're already doing with IMAP mail, iSync across multiple macs, sharing calendars, etc.
Its going to be hard to justify that price.
What do you people think? and why doesn't safari have spell check built in?
