Gurnaldo - It's far from a matter of "fanboy" issues. MANY are here becuase we have used EE, AIMON and w/e else is out there. So many of us myself included have had experience with multiple kbm adaptors. Once we found the XIM and tried it there is no comparison.
I will say this and do not take this the wrong way but I think it is a matter of preference for you. You may not notice the difference. Some of us again myself included have played PC games and played competitively. Therefore we do in fact notice every small difference. Since you have not used the XIM and most of us have tried all the other products out there, don't just assume we don't know what we are talking about because you will be dead wrong.
FACT - People here have searched, tried and tested the biggest names in kbm adaptors out there and NO other product yet, has even come close to XIM's performance.
