Ok, it seems there are multiple ways to keep files in sync between a laptop and a desktop (assuming you have MobileMe)... 3rd Party File Sync (eg. Choronsync)... Desc: - Keeps local copy of files on both machines Good: - Performance Bad: - Need to actively schedule sync - Requires extra software/expense iDisk... Desc: - MobileMe file store that can be setup with aliases to be seamless Good: - In the cloud files accessible from everywhere - Can be setup to automate sync Bad: - Slow file access performance Back to my mac... Desc: - Keep files on one machine Good: - Simple Bad: - No offline access - Poor performance from remote machine These are the major methods I'm aware of. Of course, beyond syncing normal files, there's also the issue of syncing iTunes and iPhoto libraries which can really only be accomplished by 3rd party library sync tools. My conclusion is that using 3rd party tools, Chronosync, iPhoto Library Manager, etc. is likely the best solution for performance, although not for seamless convenience. It would seem this is one major shortcomming in Apple's OS/MobileMe/iLife offering. Anyone got any further thoughts on this? How do you do it?
