Have you read 'em? I went through a period where I read them almost constantly, from the first one onwards. I've only been reading The X-Men, though, not the others like X-Factor or The Uncanny X-Men (although I have dabbled into X-Factor for a few comics because they were carrying on the story between different series in an annoying way). I think I'm up to X-Men #284 or so, which is still back in January 2005 apparently. Yikes! Got a long way to go yet.
