Actually, the prices listed in the thread are old. You can find one today for $2250 before a $100 mail-in rebate (i.e. $2150). Of course, if you want the extended warranty that will take you up closer to $2500.
These systems are getting pretty good reviews from everything I'm reading. Even though the price range is closer to the 8886, the longer battery life, a *lot* less weight, ability to have two hard drives with the smart bay, SD card slot, built-in wireless, the cool cPad, UXGA LCD, 60GB 5400rpm HD, and the overall sleek design (IMHO) are all reasons to consider it.
Having said that, there's no bones about - the 8886 is the *complete* desktop replacement. As long as you want all the extras, and don't care about the size/weight, the 8886 is certainly the best choice.
