Just wanted to throw this out there. I bought a Rev A because by the time Rev B comes out, my old PowerBook (a 15" G4 1.67 (not the most recent one)) would lose its value. Even now, the market for Powerbooks on eBay has taken a hit. As it was, I sold my Powerbook the week of MacWorld Expo and basically got what I paid for it (I got it as a great deal on eBay last summer and sold it for a little over the average price on eBay back in January). I needed that money to pay for the MBP. With the money I got from the Powerbook sell, I ended up paying about $100 more for the MBP. If I waited until August (or later), my Powerbook wouldn't be nearly as valuable or in demand. Heck, check out the threads. When the question is asked, everyone is quick to tell people NOT to buy a Powerbook.
