The objectives just changed in '06 so it could be another year before they make major revisions...maybe 2 years (though the only people who know this are CompTIA people ). If you have the time and the resources, sure, start with A+ and NET+, then consider maybe Sec+ or the Linux ones.....if of course these are areas you are interested in. What sort of IT work do you anticipate pursuing? Because if you don't wish to work with hardware (aside from changing a PS or NIC on occassion) there may be little need for an A+ when you could begin moving through your MS or Cisco certs. Simple answer, yes, you can start if you'd like.
