Actually, I was just thinking the best value of any Mac notebook has become the boring White MacBook! Seriously, with $100 off on any number of sites plus no tax it's a real deal! If one doesn't need FireWire, it will do everything the 13" MBP will do! If I absolutely had to buy a brand new Mac notebook right now it would be a WhiteBook! If I could buy any current Mac it would be a 27" iMac. If I could buy any refurbished Mac it would be a 1.86 GHz MBA for $1349 including SSD.
Seriously though... you cannot go wrong with a WhiteBook. Now more than ever, the WhiteBook is very relevant and most current Mac notebook for the money/value. It comes down to value and what one can do for the money. It still has 7-hour battery, still has nice C2D CPU, still has Nvidia chipset/GPU, and still can accept 4 GB of RAM for a few years of usability. Oh, and still can drive up to a 30" ACD!
