Apart from cost. What other reasons did Apple change from Titanium material in the G4 to Aluminium unibody.
Do you think apple in the future may adopt another material apart from aluminium for the macbook pro?
The TiBook was nice looking (when it wasn't busy flaking off its paint), but it did have its issues. For one thing, Titanium had a nasty habit of cracking when dropped hard, as opposed to bending. Not overly pleasant. Also, the wireless range on the TiBooks is horrid. It was a blessing when the AlBooks came out; they're quite nice, the design carried well into the MacBook Pros, and the newest unibodies are even slightly nicer. Personally, I still prefer the older Aluminum look, but I'm a little nuts anyway
Also, lets get one thing straight here that most people seem to get constantly wrong. It's time for a good old fashioned Timeline of Apple Products™! This episode, metal-clad laptops!
1. Titanium PowerBook G4 (2001-2003) - Made from Titanium, they're a very distinctive design. Black keyboard, metal body with white accents, AirPort antennas in the main body of the machine.
2. Aluminum PowerBook G4 (2003-2006) - Made from Aluminum, this is one of Apple's most well-recognized designs. Everything silver, with small cutouts in the top sides of the screen for the AirPort antennas.
3. Aluminum MacBook Pro (2006-2008) - Extremely similar to the Aluminum PowerBooks, they differed in subtle ways; easiest bits are the iSight camera above the LCD and the absence of the antenna cutouts on the sides of the screen. They're in the hinge bit, called the clutch cover, under a rubberized cutout.
4. Unibody MacBooks and MacBook Pros (2008-¿) - Apple's latest design, these harken back to the TiBooks with their silver aluminum bodies black keyboards, but have a much more rounded, smooth design, and more prominent black accents, such as the screen bezel.
