NickAu1, looks good to me!
I've been using Mint/Ubuntu (mainly Mint), since 2009. The terminal is a lifesaver & the commands for many issues can be found through Google searches of what's needed. Though it can seem to intimidate at first, getting work done/things fixed is far easier via the terminal (same as cmd in Windows).
That's actually the way things used to be, there was no double clicking of .exe files to open things/install apps. Too, having knowledge of the terminal is having more control over the computer, in a very secure way.
Linux Mint is also one of the more friendly distros in the Linux world, great for newcomers & pros alike. As jonuk76 has stated above, the XFCE edition of Mint is great for low spec computers, have installed it on a few myself. It's trimmed down a little, however is a feature filled OS. And far easier for the newcomer than OpenSuse.
Remember, all of these OS's suggested can be ran in Live DVD mode to check for compatibility issues before install. In the past, I've booted from such DVD's to read email, make transactions, anything requiring a secure environment. It's also the best way to try before deciding. Though it will run slower on DVD, you'll still get a feel for how it runs. If a Flash drive installer is used, it's faster.
