I was expecting an influx of old Mac Pros with the release of the Harpertown MPs this week. Marketplace isn't exactly buzzing with people offloading theirs. Local forums like Craigslist as well (scams notwithstanding). I'm not sure what the general consensus is regarding buying old versus new but the topic of the Harpertown discussed to death, is it really worth the extra coins to upgrade for most people? I guess with the little to none existent sale ads people are not upgrading in droves. Or, is it possible the mass exodus will happen later rather than sooner? I'm looking for a deal, possibly $1,500 for an old Mac Pro if that's at all possible. Any ideas on this strategy? Thanks.
