MSFT and INTC may have been late to the party but they are both turning up with good competitive products now, Windows 8, Medfield, Clovertrail and soon Clovertrail+. Tegra revenue is probably about the same as Atom revenue now so that is not the best example of the FUD you are trying to portray ;-). PC revenue will pick up again in 2013 anyway when Windows 8 and especially Haswell strut their stuff so all the gloom and doom merchants will have to find a new bashing angle ;-).
Nvidia's profit still comes from its gpus which are still totally reliant on high performance Intel cpus to sell so be careful what you wish for ;-). With a bit of luck the Tegra division, CPB, might have come close to breakeven this quarter but that is not certain until the 10-Q comes out.
