recently ive been noticing that my powerbook has finally hit its peak and is not on a downward spiral. i love my 12 cause i take it with me everywhere i go, but recently i noticed its been sluggish on the videos. not to mention is doesnt support 720p so 1080p is out the window. im very sad and i was wondering if it would even be worth purchasing leopard. even though i meet the minimum requirements i cant help but feel that its going to be even slower.
