I gotta say I'm behind Wilbur on this one. Logitech has always made decent products though, it's just that lately (and especially with Vista) their drivers have been a horrible, horrible, horrible mess. I have always been very serious about mice (used to play quite alot quake/qw around 1997-2001). I even ordered the first Razer "Boomslang" 1000 dpi back in the day, and with shipping half way around the world, customs and all that shit, it was pretty expensive to put it bluntly. The reason why I've used Logitech products is because until recently they've been the only alternative with multiple programmable buttons. My view on the matter is that you should always keep your hand on the mouse, but you don't really have alot of buttons, and so most of your fingers just rest there unused, while your left hand is working overtime on a million keybinds. Back with Quake you could instaswap weapons and fire them immediately (through scripts), so it was pretty popular to bind a key to a script that both swapped weapons and fired them at the same time. One day I got a Logitech Mouseman with 6 buttons if I remember correctly, and with that mouse I could program direct fire with 5 different weapons directly to the mousebuttons (one reserved for jumping) freeing my left hand up to soleley focus on movement, tricking, dodging, bunnyjumping etc. Since then I've just wanted more and more buttons on the mouse, but there hasn't been many other products other than Logitech with this feature. Nowadays I'd reccommend Razer, and I will invest in one or more myself. I'd give Logitech products 9/10 score, and their drivers a -10/10 score, ending up at a total of -1 point.

Then theres another problem on Vista, and really...Vista has been out for over a year, you'd think that a company with income like Logitech would have a solution out by now. You'd think... I've no idea what the problem is (and neither do you, so don't come suggesting shit like updating drivers and that kinda drivel), but while pressing some buttons, or combinations of buttons (on the mouse) while moving the mouse will cause some strange movement to occur. It's almost as if the cursor gets reset to some position on the monitor, and starts the move from that location. Extremely annoying.

Binding ALT to one of my mousebuttons (one of the thumb buttons) is something I've been doing for years. This allows me to have virtually 2 keyboards under my left hand, almost doubling the amount of functions I can activate, simply by holding down the thumb button on the mouse. This of course recently got broken in the Logitech drivers. So I had to work for hours to find a workaround (it seems Alt+tilde works, since the tilde key normally doesn't do anything). I'm just fed up with Logitech. It's all about money for them now. Back in the old days it was about gaming, breaking into new territory...now they're just pissing on the customers, since they're making money anyway.

Edit: Appoligies for the double posts. I'm at work, and these computers need to be put out of their misery, along with the streamed internet connection, controlled by this communist nazi government. (Can you tell I'm aggravated?)
