You're right. I checked into doing this. The problem is that the Webtop mod messes up the real laptop accessory (doesn't it?) and the HDMI mod too. So I have separate versions. Next versions will include the option of having all of them.
Yes I'm pretty sure that's true but at least in my case I don't have said device so these two mods, in a sense are saving me a boatload of money.
On a side note I hope my enthusiasm for this theme doesn't come across as annoying.
