In the last year or two my working life has pretty much moved from a traditional office based setup to an almost purely online existence.
These days I rotate between a office Laptop with a big screen, a desktop at home, an ultra portable netbook and an iphone. Each device has its time and place, but it has always been a nightmare keeping everything in sync, from contacts to emails to passwords to documents. This was even more of a pain every time I had to re-install any of these devices.
Well, now it is a different story, and those about to re-install as part of their Windows 7 upgrade should take note.
