Neos, im from Holland too. And yes, everone who buys a wii at my place buys it... My cousins have it now, even my uncle, 5 friends of mine have bought a wii too and none has an X360/PS3. However 2 of them formerly had a PS2 and one owned an Xbox.
My point: 'Non-gamers' pick it up, like it and buy it because of its low pricepoint. Everyone is in love with Wii sports when they first try it...
However: PS3 is still 600$ in my area (Nijmegen) And NOT SOLD OUT whereas the Wii is, EVERYWHERE...
Btw, the wheather is great, 20 degrees Celcius . In early spring...
