Well, I'm on my 3rd or 4th hour Using my Panther XL and now, for the first time, I'm beginning to hang with the big(ger) boys. At least now, I seem to be hanging in the middle of the bunch, which is something I've NEVER done (feel free to check my dismal Xbox stats).
Irregardless of this tiny improvement to most, this has been a monumental change to me, giving me new hope for the Xbox, and adding a "fun factor" I haven't had in quite some time. Best of all, my kids and grandkids all use the Xbox. Maybe 'ol grandpa can give the little whipper-snappers a run for their money! Or maybe not. My oldest son always ranks in the top 1-3 in his games, and he uses a conventional Xbox controller. Some seem to be quite fluent using the Microsoft Xbox 360 Approved Swizzle Stick. To each their own. Im also betting since the XIM3 has been released, many of these "whipper snapper's" have probably received a well deserved spanking from somebody sporting an XIM3 and their favorite controller. Ahhhhh...... Life IS good

Also noted, no matter what, there is always gonna be someone better than you. The XIM doesn't make you a great player, but it DOES give us the opportunity to use what feels best to each of us, and from hangin on this board, it is indeed a very diverse collection of controllers. In spite of this, I presume there is always gonna be a young un with better reaction time than me to put me in my place, but that goes with the territory.
In my last game, I had a guy swear I was using some form of "rapid fire", which to my knowledge I am not, unless the XIM3 or Panther is giving me an edge.
