Getting VC feedback on the idea early (before proof of concept), regardless of investment interest, is very worthwhile in terms of the LT potential. While angels are domain experts and are far better at understanding the problem / solution, they typically lack the investment track record to offer the same kind of feedback VCs do since they evaluate concepts for a living.

That said, I agree with Umair that in large part, many VCs have lost their way in terms of understanding risk / reward for these kinds of investments and use the excuse that the idea's potential isn't big enough as a crutch :

But, how would you plug all those Apples into the IBM mainframe they use for all their batch processing? :P

Trust me, a good start would be to get the Obama family loaded up and using a family blog site, powered by Apple / MobileMe, using that equipment. That's the market they want.

Good stuff.
