Try it. It may change your mind.

Actually, I already use the SteelSeries WoW mouse. I've had it for a few months now, and I'm still trying to teach my fingers to use all those different buttons.

But more to the point, I was merely curious about the nature of the article. It reads like an extended advertisement, or at least a review.

@Hal: I have been using the WoW mouse for almost a year and a half now. I have slowly added macros and abilities until I use every button on it. I absolutely love it and can't imaging playing without it now.

I am pretty sure that the Razer would be the same way. More buttons ftw. Although I think the Steel Series are better placed, but that's just me.

Yea, isn't it amazing what is considered an exact fit?

Yeah, I've been using a razer since about last October, when I wrote my own version of this article - http://www.castrandom.com/2009/10/greatest-mouse-in-world-razer-naga.html

But the Naga really is a game-changer of an interface object. Scoffers might scoff at the pricetag, but $50 is easily what you'd expect to pay for a decent mouse anyway, so $85 isn't all that unreasonable, especially considering how intuitive it becomes. It's especially great for healing - as a mediocre priest, I regularly cast flash, renew, PoM, shield, greater, circle, PoH, guardian spirit, abolish disease, dispel magic, and binding heal with some regularity. Yeah, I could fit that onto a 5-button mouse with shift- modifiers, but it's a lot easier to get it on a 12-button one without, and save the shift-modifiers for less-critical stuff.

I've been using the SteelSeries mouse since December and it's a marvel. My feral druid loves it and my Holy pally can't live without it. Kitty DPS is much more manageable with it and with the use of mouseover macros + cliqué, I don't need addons like healbot or grid for my pally. I have a bar on bartender with all the macros and skills I want to map to the mouse, and since the game natively supports it, I just bind the buttons using bartender's interface. It's really that easy.

Btw:

This macro has exactly the same function as the macro in the article. But it saves a lot of space :)
