This attach rate nonsense is so Microsoft PR from 2007 - If you look the Wii sells a lot of software - selling more software overall than the other systems. Wii games also tend to have better legs, selling fewer in opening weeks but selling much more overall. If you look at the weekly software sales lists its dominated by Wii/DS games.

The Xbox has some drastic differences - twice the RAM, a much faster CPU, 2x the polygon draw rate, AC3 encoded in-game audio. a hard drive, built in on-line - but again - none of that really matters, it was about the games. Its not the size of your GPU, its how you use it. Too often graphics are a crutch for uninspired and uninteresting gameplay - PS3/360 games are like the latest examples of hollywood blockbusters who substitute explosions and visual effects for all the other things that make a movie good.

Did the PS2 persist once the Xbox came and reduced the PS2 to a graphically "watered down" experience. Its not the tech, its the games - the first time Microsoft or Sony show the ingenuity and skill to produce something as intuitive and universal as Wii Sports or Wii Fit, then Nintendo might have some competition in the "casual" arena. Until we see some games and support Natal and whatever the PS3 motion controller is called is nothing but a Sega Activator/Eye Toy/Six-Axis wannabe and not a real factor.

Ummm have you tried it - yes you can launch games directly off SD card it takes a few more seconds to launch but it works. You need free space on your Wii to launch (it copies all or part of it to internal memory as it launches - sounds slow, but it seems much faster than the normal copy/move to SD)

Some of this is due to big developer "ego". Ignoring the Wii/DS because it isn't as sexy as the big consoles - trying to dictate to the market then listening to it and changing your strategy accordingly. Its how the movie studios work - lots of sequels/remakes - things with a built in audience or some kind of a sales hook. Lower budgeted titles can be original or take chances and every so often - they take a big gamble on a big budget original title. With the cost of these PS3/360 titles - many of these developers are putting all their eggs into one basket - and without a hook - its more likely to fail bring the company down with it. They should be spending time - with the DS/Wii/XBLA/PSN and using lower budgeted titles to innovate - create new IP, new types of gameplay - take big risks - but be safer with your large budget titles.

Many of these problems can be solved with an iPod or similar device ... its amazing how you can eliminate all the unwanted noise. And as far as metric, its a lost cause. If your average American can't see the benefit of widescreen DVDs vs pan and acan - what are the odds that metric system will make much sense. Of course, it just gives us something else we can be elitist about.
