err... sorry again... got 1 major question... after we buy an PB, we can't upgrade the HD anymore? must i do it when i order it or can i buy it later? and if i buy the ibook, will i be able to use those features in Tiger like widgets (i think that's the name) in the dashboard? i dun care much for the visual effect but more so of the features... the Mac evangelist oso said that the ibook is more sturdy and can withstand more knocks, in case i wanna throw my laptop at someone or something..
