I have no idea whether the Zune will be successful or not. However I can say that this is unecessarily biased. They state that they installed it on a second PC without any issues. I myself can attest to installing the software without a hitch (don't have a Zune yet though). The marketplace is very nice. Search is instant (as in it displays results as you type your query like desktop search) unlike Apple's software. The software is snappy, at least as much so as iTunes. I've installed both iTunes and Zune marketplace now and I have to say they both take about the same as far as effort to install. You can always download the software and install it before you buy a Zune to see if you have any problems.
Of course they were biased. It wouldn't be news worth reading if they said the install went fine on the second try.
