I've been using this for about 8 months now and this thing is fantastic, I work in excavating as well as a surveyor and this little thing goes everywhere with me. The screen can be seen in about any lighting condition, direct sunlight is a little sketchy but still usable. The battery life (for me) is about 2 weeks, really depends on what I'm doing though. If I'm really using it for work and then come home to mess around on the internet I'll get about 10 hours sometimes 11 hours but that's really pushing it. The screen size is pretty nice it's only 11 inches but for what I really do on it I don't mind, if I need to do more I usually get on my 17 inch but for timesheets and excel this little thing is nice. Performance side of things this thing runs great, 99% of apps open in seconds. For the money this is a fantastic machine, perfect size for on the go, responds instantly, and lives all day or more in my case. The only thing I would say I don't like is that only 1 of the 2 USB C ports will charge it, would be nice if it would work either way.
