Snowboards have changed a lot since 2002.. Traditionally boards were cambered, then about 4 years ago rocker started becoming a big trend. Now, snowboards are either cambered, flat, rockered, flat under bindings rockered on the tips, or some have camber underfoot rocker on the tips. If you are looking for a jib board, rocker on the tips is super nice, but as far as carving, you can't beat a cambered or flat board. Not a Whole lot of boards are flat but the K2 slayblade for example, s.
Now, for bindings.. yeah they have changed a lot since 2002 as well! Anew focus on bindings is the contact thaat they make with the snowboard and their ability to let the snowboard flex naturally without interfering at all. Park bindings tend to have a lower contact pecentage with the snowboard and allow for great flex. Park bindings are also softer and allow for more mobility making it easier to tweak things out a bit. All mountain bindings are a little beafier in construction and offer a more stable feel and solid contact with the board, also allow less movement of your foot and ankle so you can really power into your turns.
Boots... Yep, drastic improvements have been made as well! I prefer boots boots with an (articulated cuff) meaning that the boot is sort of made in two pieces so it doesn't bunch of by your ankles when flexing forward. Also, new lacing systems have been incorporated! There are still traditional laces which I actually prefer. There is also the BOA design which is a small metal wire taking the place of the lace. It is tightened by turning a knob on the boot. The other desing is the easy lace system. This sytem has a string that you pull on, then they lock into place and stay tight throughout the day. Kind of idiot proof but yes I have seen many people screw it up.
Hope that helped you out a bit. Let me know if theres anything else you want clarified I'm a profesionally certified snowboard instructor so I know a bit about all the new snowboard technologies. You may also want to pick up a transworld snowboarding buyers guide, in the past they have done a really nice job explaining snowboard technology concepts and such, also give nice side shots of tested snowboard so you can clearly see cameb/rocker/flat/rockercamber/camberrocker
