anomaly: When I bought my mouse 2000 DPI was a mid to high value, because that was what was possible at the time. 6400, for example, did not exist. It wasn't there then, it is here now. That is techonlogical evolution. Technology changes and opens new numbers for us to argue over, that was all my point was.
Marketing has evolved, not technology, the sensors themselves haven't evolved that much (keep in mind that the companies that make mouses do not make the sensors themselves, all the sensors come from just a few companies, same goes for the switch). It's just like those TVs with "480Hz", "240Hz" or "120Hz". It's a marketing gimmick, TVs don't have such high refresh rates, but "big numbers sell". Remember the 64bit Atari Jaguar and its famous slogan "do the math"?
What i want to say is that a mouse with high DPI is not more advanced than one with low DPI, they're just different. Some people like high DPI, other don't. This is why we have high-end mouses being produced right now with relatively low DPI (3200, for example). If low DPI were a thing of the past, we wouldn't have big companies still making mouses that way. And we do. Heck, Steelseries itself admited that DPI means nothing, and this is coming from a company that makes some mouses with insanely high DPIs. According to them, 90% of the professional players don't use more than 1600 DPI.
anomaly: What I really want are more than two thumb buttons and need something that is big enough to fit my hand. I also like corded mice, but that is just personal preference. There's plenty of mice out there that fit these criteria but frankly, I just don't like the look of. Hence the discussion on the RAT 7 MMO, because I like it.
Exactly. Mouses are all about personal preference. Of course there are horrible mouses out there, but there are still many good options to choose from and it all depends on what you want. For example, i use a fingertip/claw hybrid grip, a big mouse would be useless for me.
