I'm tired of the 'thinner is better' progress of laptops. As a developer I want ports, I want more cooling so the fans don't run all the time. I want a laptop I can actually place on my lap without getting burned LOL. I love my old T420. Currently have P15 from work. Horrible layout because they crammed in a numpad so now the trackpad is offset to the left. If I had to buy a laptop myself I'd lean either to System76 or the Framework laptop.
Perhaps look at HP zBooks; I have one that is almost 6 years old and still kicking; plenty of ports definitely not thin.
I just looked at the current offering and the only negative compared to mine is that it seems to no longer have any USB-A ports on the left; just on the Left.
Now they can come with Ubuntu pre-installed; at the time I had to install it myself.
Only downside is the price; they start around $2k; the one I purchased was $3k, and I justified it by hoping it would last me a while. Given that this was in 2016, I think I made out alright.
Only thing I would change is I'd like a 1440p display. At 15" I think a 4k is wated, but 1080p is a bit confining.
Also, if you do get one, do spend the extra $60 for the better IPS screen; all the reviews I checked said the base screen is garbage.
Well thankfully, Apple seems to have gone in that direction with the last MBP releases. And with them being the trendsetters they are, I wouldn't be surprised if other OEMs saw that as a green light to start putting out thicker laptops with decent ports again.
