High-end computers (e.g. Apple) are a long-term investment for most people, and so it makes sense to wait for an update if you know one is imminent.
It doesn't mean we don't "need" or want one.
I totally agree with you. I'll buy the Penryn version tomorrow if it's there, if not, I'll wait for that SUPER Tuesday. Why I would like to add 6+ months of age to a 2.5-3K$ system if I still can't wait some days... weeks ? (but not too much, please Apple... do it quick)
Anyway, I don't think that guys that complaint about rumor on this site are at the right place... and if they do, are they saying that they read anyway all our replies... sounds silly.
