help me, I can't still understand the reason why wii is selling so much

@ OP; Interesting question. I believe this is the most polarising issue of this gen.
Why is the Wii by far the most successful console? Does it deserve that accolade? It’s approaching 50% market share, but why? Lots of people have an opinion, and very few opinions match. Here’s a lurker’s take on it.
I didn’t play games from 2000-2006. I had other things to do which were more important than spend hours of my leisure time in front of the TV. I had an extensive gaming background, but not only was I too busy, I felt like gaming was played out. The GC/PS2/XB gen provided nothing compellingly different to what I’d played before. The odd Monkey Ball or GTA session at a friend’s was fun but didn’t make me want to drop the money on a console. I’d played FPS, RTS, sims, platformers, stealth, beat-em-ups, shmups and most other things and felt uninspired by what litle was new on offer. So what made me re-start gaming?
I got a DSL in Oct 2006 with Brain Training and MKDS. After the shop demo of BT, I was sold. Going by the sales, I wasn’t the only one. Short bursts of Trauma Centre, EBA, Pheonix Wright etc were a new interface experience to what I had before and it completely re-kindled my interest. The Wii was a logical next step, and I had a blast with Wii sports, MP3, Galaxy and especially RE4. More recently, PES 2008 dominates every other football game I’ve played. And if it wasn’t for that speculative DS purchase I doubt I’d have upgraded to a gaming rig. I believe this is “moving upstream”?
There are millions of gamers for whom fun isn’t 4 hour sessions with 1080p and surround sound. Just as some long in the tooth gamers don’t understand the Wii’s popularity, I don’t understand why they can’t see the obvious appeal to other demographics. As if the Wii needs games like Kane & Lynch, Army of Two or Assassin’s Creed to be “worthy”. I’ve a hunch the full extent of Wii Fit’s influence won’t be felt till we see the plans for the next gen of consoles several years (months?) from now.
Thoughts?
