After a hard couple of days it was nice to stumble across this discussion of synchronising bookmarks between computers, which includes a discussion of Yummy:
“Instead, I chose Yummy. There are free and pro versions of Yummy, but even the free version (called Yummy Browser) has more features and a better user interface than most paid alternatives. I was so impressed by the free version that I purchased the $1.99 pro version, which costs less (in some cases, much less) than most of its competitors. Both versions allow you to access your bookmarks and open them in Mobile Safari. The pro version adds a built-in browser, editing features, and support for InstaPaper and Read It Later, and comes with a handy Mobile Safari bookmarklet.”
I couldn’t have put it better myself!
