What harm do USB ports actually do? I wish I had them the other day – I'd taken my TP3 home, which I'd been using as a hub including having my main PC keyboard connected into it! Trying to reach around the back of my PC was too difficult, so I had to unplug the keyboard for a while to connect up a USB drive (it's connected to a front port).
What's more concerning is missing keys. The lack of a context menu key is sad, but I don't honestly use that key often enough to be concerned. Some people will be annoyed that RWin is gone, but I'm not consciously aware of using it, which doesn't mean that I don't … I suppose I'll simply have to find out.
The glossy case looks really nice actually.
As for tenkeyless, hey, there aren't even ISO versions of fullsize yet ;-) Besides, the switches will be sold separately, so you could for example convert all the horrible FILCO Zero keyboards with XM switches into Matias switch keyboards and get TKL that way (which I imagine people are going to be doing). The direct availability of switches puts Matias on level ground with Cherry in terms of other manufacturers being able to sell boards, and the potential for community projects, which for some reason never took off with Fukka switches.
And the switches are not orange – the orange dye was affecting smoothness, so all the sliders are white. The tactile and clicky switches are still differentiable somehow, Matias said, but I don't know how yet! (Personally I would have gone with cream as that's the conventional colour for damped tactile, but otherwise, an unused hue, e.g. violet, maroon, or even better, red ALPS!!! How cool would that be ... Trouble is, if you changed the colour once better dye is found, you'd cause even more confusion.)
