They need to fix the thermal mess of the current MBPs. The fans spin up all the time LOUD and it sounds horrible. My 2009 MBP was silent unless it was at 100% CPU for minutes with the vents blocked (on the bed).
Not when idle but a minimal amount of usage spikes, like 10-20% CPU for a minute or so. IMO the fan really shouldn't be spinning up unless the CPU is really under stress for several minutes.
