okay, so correct me if im wrong, youre looking for something that reliable and meets your needs. those purposes are very similar to what a lot of large businesses need for their employees... and what they have chosen have been vested through a lot of research.
this was my thinking, so i looked at what a lot of enterprises favor and went with an IBM lenova, it has been exactly what i expected. they have a reputation for being tough (they do also have magnesium frame bodies available) and reliable, even if they arent particularly flashy or "fun". the performance certainly isnt lacking either.
