But Macs actually work with Windows Mobile better than Windows Vista machines do, thanks to Mark/Space's The Missing Sync for Windows Mobile.
You can use this £20 utility to shuttle calendar and contact information between Pocket Outlook and OS X's iCal and Address Book apps. We're most smitten, though, with The Missing Sync's iTunes integration, which makes getting playlists of podcasts and unprotected music on to a Windows Mobile device as painless as it is with an iPod.
Ever since we began seeing full-featured ultraportable laptops about two or three years ago, we knew we'd found something we couldn't live without. Now you can do everything you want to do - play DVDs, take notes, edit high-resolution photos, copy files from SD Card and CompactFlash media (without an external card reader) - all on a notebook that weighs about 1.2kg or 1.3kg. Light weight laptops make going through airport security a breeze, and we've yet to see the back of an economy-class airplane seat that will crunch into an ultraportable's display.
