The article is spot on, so true.
I registered word.gTLD yesterday, for a new business venture, called Word gTLD Ltd. The domain wordgTLD.com was held by a domain investor, who wanted $x,xxx for it.
I understand that people don't want to pay a premium to domain 'squatters' (that is, us

), for a personal site or some low-key project. I would generally buy a regfee domains as well.
But you say this is a new business venture. I think you should have an initial budget for advertising, that includes business cards, stationary, possibly a TM application and a domain name. These are business expenses for tax purposes.
Personally I have set up a number of businesses, and bought many domains, mainly for credibility reasons.
In fact I am extremely happy to own better domain names than my competitors. Especially when theirs are not memorable or advertising-friendly. It helps offset the new guy in town label
Also, I have always said that new TLDs are not a threat to domainers. People always have had plenty of opportunies if they don't want to pay a premium. It's not business lost to domainers. They might even come back to us after experiencing their branding failures.
A couple of times, we have also been contacted by end users using
similar but inferior variants of domains that we own, because they thought we were getting E-mail intended
for them.
Which was actually true sometimes. A major embarrassment, not to mention some confidentiality issues...
A lousy name can save you money on initial acquisition fees but comes with many hidden costs that must be understood...
