<p> Apple's MobileMe collaboration service for Mac and iPhone users got its true launch today with the distribution of a Mail patch for OS X Leopard. Now I'm checking out MobileMe's Windows side. </p> The full MobileMe rollout lagged iPhone 3G’s launch by a few days. I wasn’t surprised by that; the fact that mac.com was taken off-line for a considerable time preceding the transition tipped me off that MobileMe was lower on the priority chain than App Store, which was active for developers long before its public debut.The delivery of the MobileMe patch for Leopard (presumably, there’s one for Tiger, too) is the green light for users. As part of my BlackBerry-to-iPhone switch, I’m flipping from BlackBerry Internet Service (BIS) to MobileMe. Both are hosted e-mail solutions for individuals. I know BIS, which is free for BlackBerry users, well, and I trust it fully. I wonder if MobileMe, which promises OTA (over the air) sync features and remote storage in addition to push e-mail, will prove BIS’s equal over time.Existing mac.com users will see a notification dialog pop up from out of the blue that the software is available, along with a launch link to Software Update. I’m not sure what displayed that dialog. If it was Mail.app, I wish I could embed it in a rule instead of using Growl for new message notification. The MobileMe update does not require a reboot, only a restart of Mail.I haven’t yet looked into MobileMe’s Windows personality. That’s up next. Software Development
