People get too caught up in the hype. a year ago penryn seemed like this amazing progression with evolutionary performance gain. Not true. I doubt any casual user would notice the difference between a penryn mobile processor and any 2.0 ghz core 2 duo.
Wake me up when my long wait (haven't purchased a new computer since 2003) has been worth it. I'm holding off until montevina because of principle. I didn't buy last year at this time because i was waiting for SR, when it came I decided to wait for penryn etc...now, since I could have bought back then and not even noticed a difference with the next upgrade, I continue my wait.
you wait when you shouldn't, then end up waiting so that you feel the wait was worth it...and it never is. Anyway, the benchmarks shall tell the story.
