True, but this is a good starting point.
I think a lot of larger companies would be put off by not being able to get the .com too but for small to medium sized businesses with a few £xxxx to spend it wouldn't be too much of an issue.
In this case the .com has a site on it but it's a personal blog with very little content which was last updated in 2012. A prospective buyer may be able to acquire it relatively easily, it would certainly be worth asking.
