I've been using an UltraX for about 3 years now. Although it's not as quiet as it once was, PS2 turns the machine on with the space bar, the keys are wildly responsive, and of course, scissor type FTW!!
I only wish Logitech would release the G17 UltraX Gaming/Media board. It would have soft blue illumination that can be switched from off-low-mid-high and a badass jogdial that got brighter as the volume increased. The entire top of the board would have an OLED display that could be configured with whatever plugin's you wanted. Logitech would maintain a database of these much like Firefox does with addon's. The palmrest would be firm, yet plush and never make you sweat. There would be 2 USB 2.0 ports on either side of the keyboard allowing easy access for our media readers, iPods, USB Guiness chillers, etc. Mic and headphone jacks would of course be in the back along with the 10 ft cord. And the key layout would be identical to the UltraX, except the keys would have some sort of extra long durability texture on top that only fades after 5 years. Oh yes, please give us adjustable levels of tilt from 1-10.
I don't think I'm being too unreasonable...am I?
