In that article he tries to compare Ubuntu and MS Windows XP. I say try because anyone who tries, or has tried, to do exactly the same they always fall into the same traps. The single biggest trap is to directly compare any Linux based distribution with any Microsoft OS because they are not the same for what should be obvious reasons.
Further, they always do the comparison with MS Windows as the benchmark which means that the Linux based distribution is at an immediate disadvantage. How so? Well, hardware manufacturers almost always code a driver for their hardware and that driver is almost always MS Windows based. All the various Linux based distributions play catch up in this area so it is never a surprise to those of us who use a Linux based distribution and have used one since 1992.
So, right there is the first problem. Other problems are with 3rd party add on software such as Skype. Skype was written first and foremost for the MS Windows platform and later they cobbled together something for that ran on Linux. This puts the Linux flavour of Skype at an immediate disadvantage again.
Here we have someone who by his own words played with ubuntu. He never said he was serious about installing and using it. These two points are not as far apart as they may seem at first glance. He then starts to blame Ubuntu for problems that have nothing to do with the Linux based solution but are in fact down to the web site designers blocking out, or at best a semi-functional web site, the millions of users of the Linux platform.
People such as he should know better but once again we read someone who has not the faintest clue espousing on something he knows nothing about. It is maddening for us advocates to have to read such rubbish.
