The length thing is true if all you are considering is signal travel time, but the fact that it has to convert the signal to a given keystroke gives some room for delay (depending on the quality of software involved etc) doesn't it?  I know on the console side at least that there are plenty of adapters for example (like ps2 to dreamcast or something for example) that don't have long cords, but introduce a noticeable lag.  Perhaps not noticeable in some cases, but for people that play fighting games with 1 frame links for example you'll see a lot of complaining.

I was playing some some SFA3 the other day and I was also kind of wondering about lag (with a j-pac in my case) because I seemed to be dropping combo inputs that I normally wouldn't.  I also have the j-pac bound to default controls, I wonder if that's why for me as well...

Could be dude, my Ipac doesnt like Alt,Shift, Cntrl.

since changing these to B,N,M i have had no probs at all.

I bet windows enabled their "help" mechanism and you didn't notice. If you repeatedly press a key 5 times, or sometimes hold it down for too long windows asks if you want to enable "sticky keys." I believe it's for disabled people or inept typers to aid in their ability to make capital letters and alt or ctrl commands.

I may be wrong, but it happens to me whenever i have to reformat or use the ipac on a different computer for some reason.

I thought it was this at first but i have all that disabled in ease of access.

The ipac and does not have a noticeable delay when operating correctly.  The quality of the software in the ipac is very good so if you are dropping combo keys I would look at what else you have running or whether or not the mame or emulator that you are running is capable of full function with your CPU.  Some programs do slow down as you upgrade mame to higher revs.  Sorry I cannot comment on the jpac as I have not used one but I suspect it is based on the same hardware as the ipac for its main interface.
