I dual boot with Linux Mint/Windows XP on a Presario 2100 laptop and Linux Ubuntu/Windows ME on an old Evesham desktop.
The M235 works perfectly with all four operating systems, including the scroll wheel click.
I simply plugged in to a USB socket, switched on the computer and it worked immediately.
The M235 feels well made, the scroll wheel is silent whilst still feeling the notches nicely
and with smart sleep the AA (notAAA) battery should last well.
Be wary of the photo as at this time it's not of an M235 mouse though very similar, best to check on Logitech site.
(Edit to say battery lasted just short of 5 months, green light at start up changes to red to warn of low battery.
Normal home use, I never switched the mouse off manually as it goes to sleep when the computer is switched off.
Still think it's a great mouse and recently bought a second one for desktop computer.)
