Seriously. Have you used both, for extended (months?) period of time?
I've got to use, zbook14g1, zbook14g3, 840g5 (and zbook14g5, same machine), zbook14g6, t480, t490 and now t495.
#1 ergonomics
Trackpoint in hp is unusable, compared to tp. Precision sux, autodrift after a month. One plus, you can disable it, and remap keys to get four touchpad buttons.
Touchpad, different, but comparable
Keyboard? geez, don't even get me started. It's like comparing apple abomination to actual, or 5y older products.
HP keyboard is ok, if you use two, max three fingers to type, not for serious work. It was superb, and I loved it, in g4 and older machines.
And what about that thing in right upper corner? skype keys? non reconfigurable? Instead of pause/break and insert?¿??
And linux users love that? gimme a break.
That was major turnoff for me, I've preffered to get back my old g1, and returned all those hp.
#2 screen
Both sides has some awesome options, if you want to pay for them.
Most are too dim, washed out, or even low res (HDready... seriously??)
But, lenovo has that lowpower series, which I love.
And hp has that magical privacy filter. It's awesome, one and only, which I can use and recommend. And that was only reason to try that g5/g6 again and again. But no, I cannot use that crappy keyboard :/
#3 connectors
I must say, hp has upper hand here.
That "old" slide in port replicator connector is awesome. It works, always, and don't give a damn about thunderbolt.
Seriously, afair, noone used tb for replicators correctly. It's notoriuously crappy, disconnects all the time, and everyone (hp, dell, lenovo) has probems with tb. Just apple can do it properly, and thats a shame
Back to topic, hp has stable working port replicator. Lenovo does not.
Got both generations of pro and ultra replicators for t480/90/95, and let me say, it's not working good.
t480/90 use thunderbolt for connection, and you can read in many places, how hard lenovo dropped ball, with intel's helping hand, on tb3 in that laptops. Yes, all that rage was for tb3, integrated with usbc connectors, which is faulty.
And now, t495, with amd ryzen. Of course, there is only pure usb-c, which should work better, and dockstation isn't new, it's the same as for t480/90. But nope, nada.
T495 has perfectly fine working usbc, but when you try to use dockstation? things happen. It's ok, if you dont have anything connected to dock.
But lets say, you have lcd panel, or three, for comfort. If you are lucky, and insert t495 in sleep mode, with lid open, it may, or may not, work. One time, everything is fine, 1h later, nope, nothing is dected, just connected power brick. After all updates, lenovo suggests to do hard shutdown (shift+ctrl+click on shutdown windows), with laptop undocked. Then dock it, open lid, and start from scratch.
Great, thats awesome, just needed to write notes from meeting, do some drawings, spawn new cluster of machines, and run for another meeting.
#4 upgrades
Both companies have whitelisted components, so upgrade is possible for ram, and not too mutch more.
Hp may be pricier, but you can buy lte modem, ssd, or other parts. Lenovo? not so mutch. Maybe 2-3 years after release, when laptops go second hands.
But alas, dimms. Hp win there. You can have 32G ram (maybe even 64 now?).
Or upgrade to max later.
Lenovo says, that 32G is uspported, but: go and find one. That's not possible, everyone is selling 8g soldered + 8/16 in dimm slot.
There should be another one, with 16g soldered, and free slot, or just 32gb ram, but I wasn't able to buy it in europe. As usual, US have broader offer.
Finally. Lenovo won ergonomically.
I've got my old zbook14g1, and t495 + t490 from work. on paper, I'll want to preorder gen10 lenovo with ryzen 4000. But again, no, I need to test, read fine print, ask people, etc. Before buying worthless piece of plastic for 250euro.
Or maybe, hp will finally give and option to remap buttons? Or to exchange keyboard for non-collaboration in cto models?
We'll see.
Take care, stay healthy.
