I think that a lot of people dismiss all non-palm grip mice and all mice with less than five buttons right off the bat. Some people may feel that a gaming mouse shouldn't look like something that could have been bundled with a Dell PC. Isn't very fair for the G100S which is a great mouse though. I am in Korea right now and the G100S is about $17 while the G100 (PC bang edition, no packaging) is about $13. These mice prove that there is no reason you need to break the bank to get a very competitive mouse. On the other hand, specifications also sell. I am sure the Logitech put 500 hz and 2500 dpi as the max levels for these mice so it would clearly be inferior to other mice by the numbers.
