I need to write this down or else I will probably give in later in the year and buy a MacBookPro. I am not that impressed, its hardly a radical change in many important ways. The battery life is far from impressive, its not particularly light the remote control seems gimmicky and easily lost on a laptop. The design is attractive but hardly a huge step forward over the existing aluminium powerbooks and most importantly there is no performance improvement for all the apps I used day to day. Photoshop, Illustrator & Dreamweaver. As Adobe has just announced there will be no universal binary of its apps until CS3, I will hold out until then and wait for apple to include Intel's next generation mobile processor Merom, which should improve both battery life and performance.
Of course waiting 9 months will also help me save enough money to actually buy one.
