There is currently only one manufacturer producing high quality wireless touchpad keyboards, and that brand is Adesso. You probably have never heard of them, but they have been working with touchpad mouse devices for many many years. They produce many different computer input devices in various styles and colors, and most of their products are ergonomically designed to enhance comfort and accessibility. Adesso dubbed their wireless touchpad keyboards the SlimTouch line. There is the wildly popular SlimTouch Wireless 2.4GHz Mini Touchpad Keyboard (model# WKB-4000US), then they came out with the MAC version of the same keyboard (model# WKB-4000MAC, and its white in color), and they recently released an ergo-curved model (WKB-4100UB) with the built-in touchpad on the right-hand side, which is a highly sought-after feature. The mini keyboards use four AAA batteries and the ergo model uses two AA batteries, both running off of a USB RF wireless receiver. The slimtouch mini is easy to carry around with dimensions of 11.75" x 8.25" x 0.5" (LxWxH), and the actual touchpad area dimensions are 2.8" x 1.75".
