I use this computer in the field for my business as a large animal veterinarian, and after one week of use I have been thoroughly impressed with the u it’s durability and performance.  It arrived from ToughTech in essentially new condition, and everything operates like new and as it should. The battery doesn’t last as long as I’d like, but the RW DVD/CD media drive is easily replaced with an auxiliary/secondary battery.  The screen is fantastic outdoors, if a little on the small side for my taste, but it’s worth the compromise is it is bright and brilliant without any glare, and the touchscreen feature and incorporated stylus (which ToughTech supplied with its lanyard) is killer.  The GPS seems to need an antenna for best reception, but even the fact it is there is a bonus.  Overall the unit is a little heavy and bulky, around 8.5lbs, but if you don’t mind that (which I don’t), it has the most solid feel of any laptop I’ve ever owned - even more so than my old Mac - and I’ve been through several computers in my 17 years practice.  I’d buy another one of these units in a heartbeat, and would recommend it to anyone looking for a durable laptop for field use.
