For out of the box functionality i would go for Suse or Red hat, Fedora isn't too bad but aimed at the workstation
Suse have a very nice install program aimed at new users, they are trying hard to make it as easy as possible
Which ever version you get, you can download applications to do the job you need, what ever it is
So far i have not come across any driver issues, i don't use technology that came out this morning though, if its a good brand name like HP/IBM or Dell then you should have no problems, HP and Dell even support Linux themselves
There's a bunch of automation stuff out there, some have good GUI's others are for the die hard users
You can use exceed to remotely control a box from windows, works a bit like Remote Desktop on Windows, or VNC into it from any OS
End of the day, if your a Frank Spencer it would be best to keep to Windows, Linux does have a learning curve but can be get to grips with fairly easily, once past the learning curve i find nothing is better
