I thought I would mention how good I have found the latest version of Linux Mint 7 to be (Linux Mint is based on Ubuntu) after trying it for a few days and how the problems I had previously with Ubuntu have been fixed,
I've used Ubuntu 8.10 for a while (dual boot with XP) and it's only a few little things that I couldn't get working like Java which needed installing but I gave up trying to install it because the d/load from Sun was so insanely slow, this issue is well know and was mentioned in "Micro Mart" magazine when they did an article on installing and using Ubuntu but all that is sorted with Linux Mint 7 and java and flash are installed by default and WiFi cards drivers are better supported, I don't have WiFI but my Ethernet cable connection was detected and connected in seconds and I was on-line.
There are plenty of integrated media codecs and playing some flac tracks and DVD/CD's was no problem and with the Totem movie player you can also search for and play Youtube vids, Linux Mint is a community driven distribution and has tried to deliver what the forum members asked for and this makes it a really user friendly distro.
Linux Ubuntu/Mint distros just keep getting better and the reasons to use windows are getting fewer, there are some programs that won't work on Linux but with 1000's of apps in the linux depositories you can probably find something to do the job so playing games is for me about the only reason to use windows any more.
If you've tried Linux before and not got on with it but would like to give it another go then Mint is really worth trying and you can run it from the Live CD so you don't have to install it to try it, I find it amazing that you can get an OS like this for free
You can find out more and d/load Mint from here.
