I have G4 DP 800. I don't think Aplple will release 2G Mac pro very soon so I'm considering to buy Macbook while waiting for new Mac pro. Is Macbook faster than my G4? I mostly work with Flash 8 and photoshop cs2 and they are bloody slow.
Generally speaking, the MacBook will beat any G4 based machine hands down, no problem. Remember however that PS CS2 is not Universal Binary, and isn't that snappy running under Rosetta... (not sure about flash)
