As for the Razer Naga, you're just another person who don't understand how amazing the mouse is.
Please, explain. Not sacrasm, I just want to know what is so amazing about the razer naga versus say this or this which are both around the same price but have more buttons (13 and 15 respectively) and the buttons aren't a phone pad slapped onto the side but are actually intelligently placed for ease of access. Everyone I know with a naga says the last three buttons are unusable because of how far back you'd have to stretch to reach them. I personally don't use razer mice just because I hate the shape (I prefer the flatter design of the logitech g9x or the cyborg mmo 7 since I use the claw grip style).
Arguing headphones is useless, so I won't even start.
The people who you personally know own a Razer Naga and say they can't use the last three buttons which are 10, 11 and 12 have issues - either they didn't train themselves to utilize the mouse or simply put have a small/big right hand - also, you don't freaking keybind buttons to your priority and second priority buttons to places you can't reach. Those are meant for Cooldowns. The Razer Naga sports 17 buttons in total. The buttons are frustrating as hell for any new comer. It could take a person from a week to two months depending on whom they are and how much time they've invested in total in order to master it. It took me 2 weeks to get the hang of the Razer Naga. I remember the first two nights raiding was a nightmare and I was at the bottom of the DPS meters. Also, there's nothing wrong with "phone-pad slapped" design. They're smooth when you click them and I've had the Razer Naga since early 2010 (don't remember when I bought it).
Let's dig a little deeper with this - and hopefully the water I'm spilling is going inside the glass of cup you have in order to understand how to utilize a gaming hardware efficiently - not blindly and then complain about it because the person lacks knowledge and skill. Open your mind and do critical thinking please: I got the mouse around the same time as another Warrior, we both practiced hard back in ICC25 HM raids and mixed up some bad buttons around. For example, I had some of my priority buttons on the mouse (1, 4, 7) and second-priority buttons on (5, 8, 10, 12) and my third-priority buttons across anywhere.
Everything else was keybinded from ` to 5 on my keyboard, with Z, X, C (and soon B, F, G, R in 2011) and ALT 1-4, F1-F4 were also used on the keyboard. I had my set up done that way and his set up was similar to mine. I personally didn't enjoy my priority-buttons on the mouse and had a real issue trying to master 10, 11 and 12. My rotation (going to say it again, Warrior Class Rotation, Spec'd as Fury for patch 3.3 - Lich King) was not organized so I couldn't demonstrate it fast enough.
For example, my rotation as of now in patch 4.3.4 as Arms Warrior would consist of Mortal Strike, Colossus Smash, Overpower, Slam, and using Heroic Strike between 35-60+ Rage (basic standard rotation for Arms) - Say I have my MS on my mouse for button 1, and my CS button number 7, then my OP as button number 3 ... it's like ... my rotation is all over the place. Do you follow me? This is how it was back in patch 3.3.
That was the trouble I had in the first two weeks. I moved my priority rotation on my keyboard from 1 to 4 (execute included, Slam not included and later Colossus Smash not included on the keyboard too but rather on the Razer Naga). I still had trouble with some of the keys I had on the mouse. So then I went ahead and rested my right hand on the mouse to see the actual weak points and strong points on how fast I could hit the keys. I got a big hand - sure. Buttons 1, 2, 4, 5, 7 are my fastest hitters - Buttons 3, 6, 8, 9 and 10 were my second fastest hitters. Buttons 11 and 12 were at the buttom and so they were my slow hitters. I quickly moved my CDs (Cool Downs) to 10, 11, and 12. I added another cooldown and not-so-used button to 9. My main key on the mouse was 5 and 4. My CS was added later in Cataclysm in 5 and for 4 I added Rend (which will be replaced with another fast hitter for priority or second-priority button in MoP since Rend is being removed, YAY!)
For 1 I did my stance-dancing between Battle and Zerker. 3 was used for Slamming, and 7 was used for Sweeping Strikes + Cleave macro. So much easier to hit and utilize. If I were to put those buttons somewhere else on the mouse, say CS on 8, or 3 then it would be pretty frustrating to hit that button - THATS where people make the mistake. Your priority and second-priority button hitters need to be easier to access between your two hands/fingers. My not-so-used 3rd priority buttons were on 6, 8, 9 and sometimes 10. My number 2 on the mouse for toggle-auto run to turn it on or off. I needed that.
The next buttons I added to the mouse were for my index finger to press the two buttons on the left click. They were my running/agility or speeders. My charge was added to ` on the keyboard since Charge + Mortal Strike (keybinded to 1 on the keyboard) should be your basic opener. Later at the end of Lich King and beginning of Cata, I added ALT to some of my RN buttons ... not all of them but some of them to gain access to more utility and then I added CTRL + RN buttons. The actions I added were rarely used and only good for when the opportunity comes. For example, Disarm is a 1 minute cooldown, used for PVP, thats my CTRL + RN 4. To place back my main weapon, it would be CTRL + RN 1. Few things like that.
BTW, this is coming from my perspective as an individual being with my own knowledge, skill and mindset - don't sit there and quote things off of here because other people mastered RN differently and I've spoken to them - and I've spoken to people who cried and complained about it because they couldn't utilize the buttons efficiently - instead, they put their skills awkwardly and didn't really take the time to see their own strengths and weaknesses. And some people think that the Razer Naga replaces your keyboard ... In MMOs, you are utterly wrong (games like WoW, for example). Some people didn't know that you could switch the option on the back of RN so it could replace the numpads on the keyboard, and then they complain about it because they didn't know you could do that! Just ... wow ... really.
You go on YouTube and look over Razer Naga Realtime Game Footage and see those that are able to utilize the mouse with ease. I hope we could come to an understanding. If you don't understand what I said then sure. But do note the mouse itself is a good fucking mouse and many raiders from mid to top end raiders use the Razer Naga in WoW. If you come across people that don't know their own strengths and weaknesses and couldn't utilize their own game-play style because its hard to figure shit out, then that's their own problem.
While we're on the same page, I like the designs of the mice you showed me. They'll be useful for certain MMOs and I'm sure I can get used to them. In the meantime, I'll stick to the Razer Naga until another one comes out with similar design ... hopefully a G-series from Logitech. I still own a G5 from 2006 and compared to the Razer Naga it's much better and smoother scrolling, but not a good mouse for MMOs, at all. My family uses the mouse for their general work outside of my room.
