Today I've found another briliant feature, DropBox LAN Sync.
Let me explain. I decided today that my notebook needed a format, so I popped the recovery CD's in and after a couple off minutes, she was up and running. Now because of the format, this machine would have to re-sync the whole DropBox file collection. Now I do have a 4Mbps Uncapped MWEB ADSL service, but still, at a maximum of 400Kbps it would take around 10 hours to sync the 8Gb of files.
