I miss unit testing -- it just makes life easier.
That is not, really, a sufficient reason for a company to adopt unit testing.
A sufficient reason might be "cheaper" (and/or, "better"): which is not as easy to prove about unit testing.
The only good reason might be "writing unit tests is the best use of developers' time", which is really hard to prove IMO: and it may be true in some places, for some software, with some developers, and not true elsewhere.
There are plenty of developers who don't think the world of unit tests: including some who think that other forms of testing (e.g. automated integration/functional tests) may be cheaper and more valuable, for example Am I the only dev who doesn't like unit tests?
