I have. Every issue since Alpha. Looking forward to getting them all in trade, but you'd think more people would be talking about Spider-Man 2099: Exodus. I especially enjoy how Steve Orlando has managed to work in extrapolations of some more recent developments in present-day Marvel canon like Norman Osborn leading the Cabal during Dark Reign and Loki's semi-heroic turn after his "resurrection" following the end of Dark Reign and interweave those with the future setting of 2099. Hell, the new 2099 characters seem intriguing enough thus far to spin off a whole new Marvel 2099 line based on them, too.
