In any case I never stated that what makes powerbooks is increased R&D. I believe that PBs are a good balue even by todays standards especially the Al ones. Since our last conversation I asked my friend to bring his Sony V505 and give them a Photoshop informal tests. Most of the tests were slightly slower on the Sony V505 - his machine has 512MB mine has 640MB - and the system was a bit less responsive than mine while we were comapring the filters. On WC3 the game run a bit smoother on my computer - I am using 7B39. If I have heard correctly OpenGL optimisations are not finished yet so I expect a bit more of improvement there.
The next test was encoding MP3s while playing a DVD. PB did very well Sony did ok. Sony was taking something like one and a half minutes more - he was using MMJB Plus which is supposed to have fairly fast encoding - the files were WAV ripped on the disk in order to isolate CD speed differences. The movie on the Sony had obvious choppiness when ripping while the PB seemed not to lose a frame.
In any case I felt that the 12" PB faired very well in contrast to a similarly equipped similarly sized and priced laptop. And so did my friend. I don't know how the 17" would fair against a monster like the 2.8GHz P4 17" Toshiba - I guess it would be slower - but I think that the PowerBook might still be more responsive and better at handling more than one tasks at a time. If you check it they are similarly equpped the only major difference apart from the processor is the better Toshiba graphics card. The difference in price is 700$ or so but the Toshiba is 10 pounds has 3 fans on the bottom is 2.5" thick. There you pay sleekness and portability.
So maybe the 15" lags behind a bit and yes the 1GHz G4 shows it's age. But given how old it is it does very well. I guess you can attribute that to the effort of Apple to provide efficiently written software for a slower processor in order to compete. Watching my 867MHz PB ripping and playing a movie effortlestly - the fan didn't kick in even once the sony fan was on most of the time - while a processor with 2.3 times the MHz of mine barely keeping up made me an even prouder owner of an awesome little 12" PB...
