On gaming mice: I don't need anymore DPI. I'm not a gamer, so buying a gaming mouse is just spending money on features that I won't use.
On the latest wireless mice: I have tried new wireless mice. It's not the efficiency of the mouse it self thats the problem. It's the fact that they all use AA or AAA cells. Therefore, I have to eventually remove them, charge them, and replace them in the mouse. Plus the NiCad batteries eventually loose capacity after a few cycles (even the nice kind like Eneloop).
The biggest problem is wireless interference and tracking latency that I experience with all wireless mice.
There still is innovation in the mouse field. Placing a touch interface on a mouse is great. From my short experience with one, I've found it to be the biggest innovation since 'scroll wheels' and 'optical tracking'.
Right now, it seems like seems like the mouse market is divided between gamers (people who want the maximum DPI and lots of programmable buttons) and casual users (people who want a simple, lightweight and wireless mouse for there laptop). Someone like myself (a computer professional, who wants something sturdy, comfortable and reliable) is no longer considered a market.
I really would like to use a mouse with a touch surface, but without a wired USB connection, the inconvenience outweighs the benefits.
Microsoft presented their new touch mouse at CES. Yeah, mice are definitely not new and exciting at this point, but until 'touch' becomes ubiquitous they are still quite necessary.
Since I still have to live with mice for the foreseeable future, I'm frustrated at the lack of decent wired mice on the market. Wireless mice always give me tracking issues and I don't like the inconvenience of replacing batteries. But every new mouse on the market is wireless now.
I'd love to try the Apple Magic Mouse or even the new Microsoft touch mouse, but I'm not willing to deal with wireless. Therefore, I'm using an IntelliMouse Explorer 3.0, a mouse first released in 2001, because new mouse innovations don't come with USB models anymore.
God forbid Ballmer, Mhyrvold, etc... pay a little more in taxes to pay for education and health in the state, which will benefit many Microsoft employees and ultimately Microsoft's bottom line.
Where does Ballmer think the money came from that payed for many of his employees K-12 education? It probably would have been far more difficult for him to find employees if a decent K-12 education hadn't been provided to them.
