I think you are missing his point about the computer industry. If you wait, you can buy a better computer for the same amount of money as you would originally have. Alternatively, you could buy the same computer for less money. This is the equivalent of your money going up in value (as in you have more buying power). His argument is that if we use the author's logic, people would want to wait to get a new computer instead of buying one now. This is obviously not the case and so his argument is flawed. I agree with the poster and disagree with the author; the poster found the perfect analogy.
Deflation, when things are worth less over time, means producers have to sell MORE to make payroll, pay their bills, pay their debts - which haven't changed in value.
It's great for people flush with cash - and horrible for anyone in debt.
The computer industry has planned obsolescence. None of them are buying 10 years worth of parts for today's computers at projected market rates, because that would be a pile of stuff they'd ahve to eventaully sell at a loss.
It's not so simple as simple analogies....
BTC is designed to be, in the true sense of the word, a trustworthy way to move value from point A to point B -and there is avery strong network effect required to make it work (or any similar currency).
At a point where I know I can go somewhere, locally, and exchange my bitcoin for local currency (and some posted market rates) - I will probably start accepting using it for a few things.
I agree that the incredible range of custom window managers (WMs) is a very interesting aspect of *NIXes and a source of innovation. I can't however agree with your initial worries about Wayland.
Wayland actually makes it easier to roll out your own window manager than X11. The Wayland protocol is a lot more straightforward and has fewer extensions. You no longer have to deal with XRender, XDamage, XComposite, etc. You also don't need to think about setups where some of these extensions are missing.
It also does away with network transparency and replaces the protocol with a simpler, more unified OpenGL ES based solution. You have more freedom to develop something original as you aren't stuck in X11's rendering system which is a glorified painters algorithm. You can use XComposite to obtain more freedom under X11 but so far few window managers use it (compiz, KWin, metacity). The default for Wayland is very similar to what you find in XComposite but is faster (given a decent video card driver) and simpler.
The only drawback to Wayland is that it is rather new and the protocol hasn't been finalized. As soon as it gains wider adoption and there are a few example Window Managers, expect to see some interesting and innovative WMs.
