Linux fans (myself included) love to argue to Windows users how much better the Linuxes are than Microsoft Windows. Now don't get me wrong, I am not posting this to disprove that Linuxes, BDS's, or any of the *nixes are better than Windows, they really are. However (and there's always a however) we tend to be very selective on what we tell you when it comes to the minor details. Take this as a confession, as an admission of those details you might not necessarily like about Linux.

1. The basic installation of most mainstream Linux distributions is very easy, but a first time user might run into trouble when trying to depart from the defaults.

Some Linux distributions have Live Cd's, others have very user-friendly GUIs. However you might find that sometimes the Live CD installer, or the pretty GUI does not work because the installer does not have the right graphics drivers. In that case, you either need to find an alternate installation CD, or change the options at the boot screen. We don't tell you that this might happen because 90% of the time, the installer will work fine out of the box.

2. If you want a proper Linux installation, you are going to have to mess around with the partition table.
