Adamo, now it's the Envy. HP has joined Dell in deeply discounting its aging 13-inch ultrathin, though unlike its Round Rock competitor, it hasn't bothered to give it any spec bumps. Consequently, even with this interest-building $450 rebate, the Envy 13 loses out to the Adamo 13 in a straight spec fight -- a 1.6GHz CPU, 3GB of DDR3 RAM and a 5400RPM hard drive are all either slower or smaller than Dell's offering -- but it does still have a pair of aces up its sleeve to get latecomers to part with their cash. Those include an external SuperMulti DVD rewriter and a discrete ATI Mobility Radeon HD 4330 GPU with 512MB of dedicated memory. Sure, it's not much, but then neither is the new price.
