Although I do agree that a technology facelift is needed to give the game a more modern feel...modern for a game that is far in the future...
There are ways to still keep the tech levels down without going all cyborg crazy...
I was introduced to traveller about 20 years ago, my Ref had been running traveller from the time he got his hands on it's first printing back in 1977.
He loved the feel of the clunky old scout ship or fartrader, steam being expelled from leaky pipes, the whole nine yards. One of the things he incorporated into his campaigns which then spawned one of the other guys in the group to create a campaign setting in the 9th Millenium, was the first appearance of the machines (a robotic / cyborg race) akin to the borg in star trek that would decimate entire star systems.
It took a combine effort of most of the sentient races to beat them and with the exception of a few "scouts", no one heard from them again, but the fear was always there...the fear that someone could be corrupted into becoming a "machine" was always there, so this kept the cyborging out craze down to a minimum and made for interesting game play when a character lost a limb...
We had a bounty hunter in our group who had a plastic prosthetic left leg and left hand...pure entertainment

Anyways, yes I think the the feel needs an update as far as clunky old computers and plastic prosthetics, if a world wants to jump ahead and create watch sized supercomputers and allow full cybernetic or bio enhanced replacements...I say let them...you can always put the fear of the "Machines" in them...
Virgo (our ref) also ran a campaign where cybernetics on this one planet were the cause of a viral epidemic...the main reason why the bounty hunter got his plastic prosthetics...
So, there are lots of ways to keep things on a lower tech level...or at least explain why...
Anyways, I am so looking forward to this latest edition...
My traveller group is up and running and gearing up...in memory of Virgo who we lost a year and a half ago...I have found myself somehow having to step into his flip flops.
