I've never been a fan of wireless devices as I frequently have far too many things on my mind to be trying to remember to charge a slew of widgets. Hard wired = powered at all times and ready for input. Any device that (isn't tethered) can be walked off with, can be lost, and that's hardly convenient IMO).
I've used these Microsoft Wheel Mouse Optical for years. They're cheap, simple, require no accessory software, and just work regardless of what machine/OS I connect them to.
I tend to appreciate things that really are effectively idiot simple.
I hear you. I've avoided wireless as much as possible up until this year. I simply found them flaky and unreliable.
For mice, I resisted optical mice as long as possible as I found that a good Microsoft ball mouse was simply FAR superior in every way. Granted, they need cleaning, but that's easy. I still find optical mouse technology is seriously lacking in comparison to ball mice, which just aren't available anymore.
Back to wireless -- I still don't like it much. The telcos here in Australia throw in an extra dose of incompetence for all things Internet. 3G barely works on the Optus or Vodaphone networks (haven't tried Telus) if at all. In Korea they even have DMB - Digital Multimedia Broadcast -- You can watch TV on your phone. And it works. But they also have a far denser population and infrastructure can be setup better -- Australia is too big to setup infrastructure of that quality. Still, you'd think that 3G would work properly in major population centers like Melbourne. Sigh... I'm ranting again...
For wireless routers... Sigh... Same disappointment. Slow. Not nearly the speeds they promise. Yet another disappointment.
On an uncharacteristic note... My Apple keyboard and mouse are both wireless and actually work pretty well, better than anything else on my Mac anyways. No complaints about that.
My HTC phone... well... the wireless works with Wi-Fi, but the Vodaphone 3G is beyond useless.
Still, the wire situation on the desk is pretty much out of control, so... Wireless mouse it is.
I hope that in the not too distant future wireless technologies mature enough to be comparable to wired - including reliability.
