RJ45 is too fat

[fanf]

One notable feature of the ports on the new MacBook is that the RJ45 Ethernet socket only just fits - it wouldn't if the machine were much thinner. In fact the MacBook Air notoriously doesn't have any wired ethernet connection at all, relying on IEEE 802.11n WiFi for connectivity.

Of course other manufacturers are making expensive thin laptops. The Dell Adamo neatly solves the RJ45 thickness problem by putting the port behind the display hinge, where the machine is as thick as the body plus the display.

The Voodoo Envy's solution is to put the ethernet socket in the power supply, which acts as a WiFi hot spot which the laptop uses for connectivity. This is cute but it means you only get 54Mb/s because the base station doesn't have 802.11n support.

A cheaper and faster alternative would be to pass a gigabit Ethernet connection through from an RJ45 on the power supply to a combined power network port on the laptop. The connector could be much thinner than RJ45 without sacrificing compatibility.

ETA: The other advantage this design would have is that the combined power and ethernet connector can use the magsafe idea, so you don't have the problem of one safe and one unsafe connector when tethered.

If my memory servers, back before the days of integrated RJ45 ports, there was a PCMCIA card that had a little pop-out tab where you could plug the Ethernet vertically. The contacts faced towards the computer. Perhaps flimsy, but certainly space-saving. I wonder why this wasn't adopted on the Air.

Yup, 3Com Megahertz FE574BT... ("With XJACK")
I still have two of them because of that very interface. (Saved me having to deal with dongles, which would invariably get half-inched.)

They still some in handy now and then too.

Oh come on Ron, you can't change a BATTERY in a current MB, and you think they'd let their precious aesthetic allow a pop out connector? Screw Apple. As much as I love OS X for some things, I'm just done with their idiotic aesthetics over function design decisions.

No need to get angry, no-one is forcing you to buy a Mac :-)

The Air's connectors are already sort-of pop-out. I imagine a lovely machined aluminium XJACK could be almost invisible when pushed into the body of one of Apple's current range, so it could be beautiful as well as useful.

No, no one's going to make me buy one, but I LIKE the dual G5 Mac Pro next to my desk. It is beautiful in both aesthetics and functionality, but functionality wins where Apple had to make the choice. These days, it's gone the other way, and I'm over it.

That was called the XJACK, patented and made by 3COM.



But lots of Ethernet card also had dongles for RJ45 (or RJ11) connectors. Clumsy, and easy to lose, or break, but they did work.

Yes, the XJACK is brilliant but flimsy. I expect you could make a more robust built-in version since you aren't constrained by the PCMCIA form factor.
