If it's stolen or lost, they track its whereabouts whenever it gets on the 'Net and work with local law enforcement and ISPs to find the machine. I'm wondering: has anyone used one of these services? Does anyone have a recommendation for which company to go with? My new laptop is a a dual-boot Ubuntu/XP machine, and the couple of companies I've looked at do Windows-only. Are there Linux options?"
