Since the passing of Windows XP, I have been trying to find a good OS for my ThinkPad R51. Even Win 7 is a drag on my computer. Microsoft does not have a solution to this - only to "install Win 10". It would be a shame to have to junk this functional hardware just because the OS is not able to adapt to the hardware.
I have not tried any other software but have looked at Linux and Ubuntu. The current versions require (?) Physical Address Extension (PAE) which is not available on my system.
As of this time I have not tried any other OS. Just stumbling along with XP and W7. 2 Gig memory maxed out. It runs W7 but the graphics is under powered - W7 and other upgrade advisers say that the graphics is the fail point. If that was upgrade-able, it appears that it would work. I have looked at Linux OS but the current releases require the Physical Address Extension available. So?
I'm just a "stupid" user with a question who can not afford to replace my multiple R51s with 'modern' systems.

I know that might be more information than you want to see, but more is better?
