So I've been pondering a mac for over a year now...but seriously considering it for a few months. Ultimately I've been waiting for a macbook update. I'm some what sold on the mid range macbook, the unibody with the 2.0 ghz cpu. The "buyers guide" (http://buyersguide.macrumors.com/#MacBook) said don't buy, end of cycle until April 1st. After the "rumors" on April 1st from HardMac saying there were going to be updates in September (of which didn't explicitly say the macbook was getting updated, and also weren't even confirmed), now the buyers guide displays mid cycle...I'm assuming that's taking into account that they believe there won't be updates until September. I need this for iphone dev...and I need it within the next month-ish. I'm tempted to buy a mini...but I could really use the portability of a notebook. What are your thoughts on the timing of the next update? Also, when did they start the back-to-school promotion last year? Any thoughts on what/when it will be in 2009?
