If they come out with a phone in partnership with motorola, I'm buying that phone (assuming there's a heavy apple brand hand on the device, not just a software addition).
About the rumors of a $500 mac (see thinksecret.com); I don't know, Steve Jobs has always seem pretty damn committed to keeping the prices high even in the face of low market share. It seems to me that if there was any hint of him wavering on prices, we would have seen the iPod mini released at a lower price. But even that tiny thing is relatively expensive. I would like to think Jobs has softened his position on pricing, but it's very hard for me to believe.
For sure we'll see something special for the GarageBand. Either a breakout box, or some equally cool enhancement.
As for Tiger, bleh, I would rather they just focus on Panther a while longer. These updates are getting damned expensive. Right now I've got one machine running Jaguar and one running Panther. I can see the differences, but they aren't big enough for me to keep shelling out dough like that.
