Several current Dell Precisions like the 7740 at least have the trackpoint nubs still. Almost all of the HP EliteBooks do as well -- the exceptions in both lines are the "thin and light" workstations. To your point, it looks like some Dell laptops have ditched the nubs in the 10th gen Intel ones, but up to at least the 9th gen Intel based ones still do, and HP doesn't seem to be giving up.
They're called different names, but same concept. HP has "PointStick", Dell has "TrackStick", etc.
