why don't you trust Lenovo?
Although, in my opinion, I wouldn't trust any laptop hardware company out there enough to use the system that came pre-installed with it, but that's for another discussion.
There was also the Lenovo Solution Center problem. And the Lenovo BIOS shenanigans (or was it the Lenovo Service Engine?).
There have just been too many lapses in judgement at Lenovo. Either their competence is slipping or their ethics are. Either way, I'm done with them for now.
What? The M3800 had terrible battery life under Windows and it was even worse under Linux.
