It's only selfishness

It's only selfishness

What does Mom do after Lindows has passed the "Mom test"? What if she tries to install the latest Windows game or cool screen saver? I still fear (selfishness, of course) that, after the initial easy-to-use appeal, many users will face bad experiences with Lindows, and turn away from Linux for years to come. This may be worse than if they had never used Linux at all.

That's called "oversell". It's not a problem if the salespeople don't make it one.
Remember, these guys do like to sell an expensive system. MSwindows-based if it is so. It's just, happy customers makes long-term income.

The right customers for these systems like to stretch their budgets. They need their tasks done with a minimum of hassle, and don't like to make things more difficult than they see a need for. Plus, they see computers as work, not play. Computer games means something on the scale of Solitaire for their own needs, but kids would like something fun and educational.
There are quite a lot of them.
If sales force please that market, that's fine. It means customers they might not have had otherwise. But the rest will have to pay for their needs, and that's even better.

And, there are plenty of moms out there who'll find it entirely all right if their kids can't install Half Life at home. Freely available screensavers can be impressive compared to the standard MSwindows ones.
