My work laptop is an M3800, though the newer one is the 5510. Pretty solid machines in my experience. We did after market upgrades to some very fast SSD (sorry don't remember which). That said- I'm staying with the m3800 as long as I can. It's a few years old and my battery needs replacing, but otherwise is very capable. Some people have had docking issues on and off with the 5510 (occasional crashing, though I think it's a driver/software issue), but more importantly it has the awful "Nostril Cam" which is annoying for video meetings. In general, fast, light, good battery (for perspective, mine lasts 2-3 hours now, vs 5-7 when I got it), useful ports. The keyboard is not the best (home/end/pgup/pgdn keys are fn+arrow instead of dedicated) but very usable. I hated the glossy screen at first, but touchscreen is surprisingly useful and I got past it. I just keep a microfiber cloth in my laptop bag now.
