I have a 7405gx...you don't have to install the media card drivers on it if you don't want to. Just stick a card in and then Windows will recognize the card reader. I think the drivers just add graphics to the icon in My Computers. The card reader software also seemed a bit buggy on my 7405gx and my brother's 7405gx too, I'd get crash messages once in awhile (like swickon.exe or something crashed). I installed XP Pro on mine and I haven't had that problem since I didn't install their drivers, I let XP do it. I dunno if the 7422gx has the same reader, but you might want to give it a try
