Tip: If you decide to use Linux, don’t install any new kernels because (dun dun dun) doing that will break stuff!
I’ve upgraded the Kernel twice since installing Linux. The first time the new one didn’t want to work with my wireless card (so I had to boot to the old one every time); and the second time – this morning – after installing the new Kernel it didn’t want to work with my sound card. It transpired that was more to do with volume control issues (i.e. the output was muted), but it took a few minutes to get into the volume control.
So, if you use Linux, be prepared to use Google a lot if you upgrade the Kernel 😉
