I understand what you mean about the function keys. It used to be that on laptops you would see the alternate functions on the F-keys, and you had to hold down something like an Fn key to use them. I see a lot of laptops these days that do the opposite, where you have to hold down the Fn key to get the F-keys, and I hate that.
Yep I think that it's quite silly to have to press Fn-F2 ro rename or Fn-F5 to refresh but be able to adjust volume or screen brightness with just F1, F2 etc particularly when many laptops also have dedicated media keys for volume at least and brightness is not something that you change every few minutes. Dell's (at least a studio 17 has) have a setting in the BIOS to swap it back to original sane settings.
