But how are you going to upgrade the OS with no optical drive and no Fire Wire? I could possibly live with the ethernet adaptor, but when do you get so weighed down with the external stuff you have to lug along with you, that you surpass the already lightweight Power Book?

And the RAM is welded in, so you can't upgrade that. But I thought you could pay an arm and a leg to upgrade the HD; could well be mistaken on that.

I'm not really computer savvy, but even I can see shortcomings to this one. That's awful, because my Power Book is 5 years old and I could have justified a new one if it was "have to have" impressive.
