I stopped in the Apple Store at lunch today. There aren't any things there that I think, "Gosh, I'd sure like to have that." Is Apple slipping in feeding the technology addiction? Not if you read their quarterly results!
After seeing future-bro-in-law's 17" MacBook Pro, I do admit that I kind of would like to have one. But I'd prefer to get three good years out of my 15", and I'm already two-thirds of the way there. It has been a great laptop, not counting the weird random shut-off thing it did for a couple of weeks. The battery health is starting to dwindle after ~250 or so charge cycles, but I'm still getting two hours per charge.
The hot rumor is that the iPhone will be re-released with support for 3G networking soon, which certainly has some appeal. I'm just not sure it's $500 appeal. The only thing I really wish it did that it does not currently is some "real" calendaring functionality.
I'll look into the iPhone as soon as they allow different carriers besides AT&T - which sucks in Northwest OH, where my parents live.
As far as the aluminum Macbook - I'm already planning on that in about 2 years. I can't buy a new one when this one is 3 months old.
