Windows Live Sync is here

If you remember the FolderShare service then you will really love the improvements that are in Windows Live Sync:

• Higher file limits—up to 20 synchronized folders (formerly known as libraries) with up to 20,000 files in each one.
• Integration with Windows Live ID.
• Integration with the Recycle Bin.
• Unicode support.
• More languages for Windows (46 in all).
• And lots of bug fixes.
