This goes for pointing devices as well as keyboards.
Personally, I understand the aesthetic of wireless technology, but my experience with Bluetooth input devices has been less than positive. Their precision (especially w/r/t mouse/trackball tracking) has been wanting, they require some extra fussing to get paired, they're more likely to have driver compatibility issues, and having the battery die right in the middle of an operation is ridiculous. And maybe I'm paranoid (*putting on tinfoil hat*), but I like to keep the radiation in my environment to a minimum.
So I was looking online for a disposable travel-mouse, ideally with a retractable USB cord, and noticed that the entire market seems to be going in the direction of wireless devices. For every wired model, there are now five (or more) wireless ones. The future for input devices appears to be wireless, whether I like it or not, and maybe someday wires will go the way of the 8-tracks.
I'm curious about the opinions of others in this forum. Do you have a strong preference of wired vs. wireless? What are your thoughts about the future of wired technology? Is this (apparent) trend justified, or is it merely something created by the manufacturers to make us buy new gear?
