Tim, you say he would be "better off incorporating in Delaware" over Nevada, but then you don't really give a reason why other than to ask if he really wants to be associated with "Bugsy Siegel" ???!!! - I'd guess most people equate Nevada more with Wayne Newton, Cirque de Soleil, and Elvis than some decades dead gangster of questionable relevance.
Using your argument, you could say that you might not want to incorporate in Delaware, because do you REALLY want to be associated with The Bruno/Scarfo Family? Do you really want to incorporate in California and be associated with The Manson Family? Sorry, but that's just retarded.
For the record, I prefer Wyoming.
There are plenty of strategies for utilizing Nevada, Wyoming, and other state tax free jurisdictions for your business, but you have to know how to use them, and they are not a one-size-fits-all solution. Nevada is great for holding intellectual property that receives royalties, or I would say for a majority of internet based companies.
If you operate and live in an extremely highly taxed state such as for instance California, you can have your main operating company registered in California and another company in Nevada that owns your office equipment, vehicles, intellectual property, etc. and leases it to your California company at whatever rate you agree to, thus draining the profit out of your California company so that you only pay minimal California state taxes. Tens of thousands of companies in California employe this and similar strategies. Many California companies are only able to be in business because they employ a strategy such as this. There is an excellent article explaining this (Dual Entity Strategy).
The reason I would hesitate incorporating in Nevada is because they aren't really what you would call "business friendly" anymore. Consider the onerous and exorbitant license fees they pile on to the already high annual list filing fees. The legislature in Nevada is loaded with public employees and other legislators beholden to public employee unions, so following the lead of California, they have been mismanaging the state's finances for years, have massive unfunded pension liabilities, and some legislators have publicly declared their desire for a business tax, so any advantage to doing business in Nevada might be a short-lived proposition.
Delaware also has been raising their annual fees to make up for their own mismanagement of revenue, plus the employees in the Delaware Secretary of State / Division of Corporations are probably the rudest and most unpleasant people in the entire country, so if you think you'll ever have to deal with them, you might consider that as well. Every interaction I've ever had with Wyoming has been a pleasant one.
