Hey Slickone,
I wish they would just leave the keys alone too. It really takes some time to get used to it, which can be frustrating.
As far as the F-Lock, MS gave the Function keys F1...F12 new abilities like Help, Undo, Redo, Save, Close, Etc..., but I'm used to the old ALT+underlined letter or function key way of doing things so I don't really like these new functions. To make things frustrating, the new enhanced functions don't match up with the older ALT or F key methods. For example, to close a program I would press ALT+F4. With the new enhanced functions, I have to press F6 for Close to close the program. This can be bad if you are working with browsers. Some people press F6 to highlight the address bar so if your F-lock key isn't set correctly, you may end up closing the browser when all you wanted to do was to type in a new web address. F-lock off and the F6 key functions as a Close button. F-Lock on and the F6 button highlights the address field in Internet Explorer. To switch between the old F1...F12 and the Help...Save functions you have to toggle the F-Lock key just as if you were switching between all caps and normal letters.
As far as the mouse, I actually really like it. It isn't too big and bulky and it isn't small either. The back and forward buttons on the mouse makes web and explorer browsing a breeze. I just wanted people to know that the horizontal tilt isn't really that great. Getting used to the no clicks while vertical scrolling only took me about a day and I am beginning to think I prefer the mouse without the clicks now. Be aware that you can no longer program the amount of lines you can scroll with this set. You can only program the scrolling speed, which makes sense if you understand that MS tried to design this set with smooth scrolling as a new feature. The smooth scrolling still results in some steppings or jumps when you scroll but it's not as pronounced as the older scroll technology. I find that the longer the web page, the smoother the scrolling works. For web sites that are shorter in length, the steppings become more noticeable.
