Copied from the Hardforum site:

I have owned the Blitz Formula, the Maximus Formula, the Rampage Extreme II and the Rampage Extreme II Gene. What I liked about them:

1 - Easy overclockers and solid performers.
2 - LCD poster - Probably one of the best friggin innovations ever and it's a shame that the new P55's have lost it.
3 - Sound card wasn't built-in, but rather a separate card.
4 - Overclocking features of the bios.
5 - I got the Blitz because of the water cooling. Granted the new boards allow for the Swiftech to be added on, it would be nice to see it included again.
6 - I like the dual BIOS chips, but I think that was only on the REII and not on even the Gene.
7 - Temp probe connections on the board.
8 - Voltage pads.
9 - The new memory slots of the Gene.
10 - Love Ezflash, keep it.

Some things I would like see:

1 - Again, water cooling integration as an option, not sure if it would drive costs up to high to have the same board with and without as Asus did with the Blitz and the Maximus.
2 - I like the color scheme of the new Maximus III, I hate the color scheme of the Rampage II and Gene. Main point here is that you stick to a two color scheme, not the full rainbow. You are building a motherboard, not painting the Mona Lisa.
3 - Loose the IDE, PATA and PS2 connectors, let them die in peace, please.
4 - Temp probe connections to work with Everest. I do not care for your software, always seemed too buggy for me.
5 - The LCD poster to be able to display a specific item, i.e. the CPU temp. Currently it's either the time or a rolling display of voltages, temps, etc.
6 - Keep the LCD poster, I do not always have a laptop laying around to use to debug another machine.
7 - Make the Micro boards just like the Big boards, i.e. the Gene should have everything that the Rampage Extreme II has, i.e. voltage pads, just lacking a few slots.
8 - Digital PMW's like the Classified and DFI board. Why? Because it cleans up the space around the CPU socket making it easier to insulate for extreme cooling. Yes, I do realize that not a lot of people do extreme cooling, but if you are going to price your board in the same price range as the Classified it should have comparable features.
9 - Being able to disable the PCIe slots individually like the Classified. This is very useful and it's an easy thing to do with jumpers.
10 - Loose the clip on fans. I do not even think they work and it seems to be a waste.
11 - Make the LCD poster mountable.
12 - A right angle PSU connector.

I have more, but you get the idea. I have always loved my Asus boards. Hated selling my Blitz and Maximus, but I was going I7. I had the REII, great board, but I couldn't get over the colors, drove me nuts. Seriously, I am hoping Asus does a refresh of the REII with a different color scheme so I can buy it. I really love the LCD poster, it makes it so easy to figure out what happened during an overclock versus having to look up some stupid code. As far as your software, I think you should do something like what EVGA did with their Eleet software and CPUz. It's simple and effective and doesn't take up half of my desktop like the Asus monitoring software. Anyway, have really loved the ROG series and Asus support, these are just some suggestions.
