I have very bad arthritis in my fingers and find it difficult to type on the keyboards wherein all of the keys are uniformly flat and spaced very closely together. I purchased a Microsoft Natural Ergonomic Keyboard 4000, for home use, which helps solve my home problems.
Is there a laptop notebook manufactured that has the individual "raised" keys similar to the Microsoft Ergonomic one described above and, perhaps, with a larger screen (maybe 15")?
I can't say this works well or not but I started searching this topic and found this right away: http://www.lightio.com - you don't even have to touch the keys.
I have a MS Ergonomic keyboard for several years, btw, and it's nice. (Model 4000). The 'gull wing' makes for easier typing, for me, but what I think is the most important feature for reducing stress and pain is the wrist-rest.
