Nimeni nu ar trebui sa fie surprins de rezultatele testelor, avand in vedere ca laptopul foloseste un FSB rapid, performanta totala este trasa mult in jos de placa video integrata, si un anemic procesor 1.6 Ghz Core 2 Duo si hard-disk-ul de 1.8 inch.Puteti numi MacBook Air cel mai incet laptop pe care Apple il asambleaza, dar cine cumpara un ultra-portabil pentru performante inalte ? Nu poti sa stai sa programezi, sau sa fii grafician pe un astfel de laptop, publicul tinta fiind probabil oamenii de afaceri.
- toate laptopurile de mai jos a fost testate cu Xbench 1.3
- si toate dintre ele rulau Leopard (cu exceptia MBP-ului din mijloc). Iar MacBook foloseste 1Gb RAM
