notebookereview.com had this review that compared Super PI benchmarks among 15" PB and several intel machines. PB 15" was the fastest and faster than IBM T43 1.86G: http://www.notebookreview.com/default.asp?newsID=2400 This makes me feel that PB is still a great value and can last a couple more years at least. It also makes me want to switch now and I'm very interested in 12" PB for its portability. I'm wondering if anyone else in this board tried Super PI benchmark for their PBs (any model), could you post the results? SuperPI for Mac can be downloaded at: http://ocing3.free.fr/FTP/overclocking/super_pi/Kanada_lab/exec_Mac_OSX/ cheers!
