After watching those videos I have just one thing to say:

Nokia are a bunch of fools. Those games would run much better on the N900 with better framerate and considering those games were made using Qt, it's very likely they would work on the N900 as well. Nokia were the ones that killed the N900, not us. If they cared about it more, it could have had the same games the N8 will get and with better support. Hopefully the 1.3 update comes out soon and devs will want to support the N900 as well. I don't need games that much, but it's Nokia's attitude that drives me nuts. Sometimes they act like a bunch of five-year-olds.
