It's those who have been holding out on purchasing because "the next big thing is coming" to the MBP since its release 2 friggin' years ago and do nothing but gripe on the forums about how Apple isn't fast enough to get newly announced products to the table in one breath and how big bad Intel is pushing product changes too fast in the next...
