If your top priority is keeping data secure, you need to protect your machine and its contents from security threats as well as from accident-prone users or other calamities. The rugged-and-reliable Panasonic Toughbook 30 is mobile-broadband and GPS capable, has a workhorse Intel Core 2 Duo processor, and is designed to perform well even in harsh environments. From a security/durability standpoint, the vendor-specified annual failure rate is in the low single digits and Panasonic says it can still function after being dropped up to three feet or less. It also has a sealed all-weather design and comes with an 80 GB shock-mounted removable hard drive in a stainless steel case and optional built-in SmartCard and fingerprint readers.
