I realise that some of these questions may have been answered elsewhere, but I'm looking for some answers from MacBook owners (or people that have used one). 1. Sound quality - What is the sound quality from the speakers? 2. Keyboard - How does the new keyboard compare to the MacBook Pro/PowerBook keyboard - is it good enough for touch typing? 3. Touch-pad - Does the touch-pad support "two finger tap" right click? 4. Heat - How hot does it get under normal use? 5. Back light - Is the back lighting even? 6. Viewing Angle - Does the glossy screen improve the viewing angle? 7. Graphics Performance - Under normal use are all effects/transitions smooth (we're not talking about pro graphics apps here). 8. And the most important question of all - Will it run second life? 9. Glossy vs Matte Screen - This issue has been flogged to death, so no need to discuss here. With your answers please state which MacBook you have/used.
