MacBook Refresh in the Works?

There has been a lot of speculation recently regarding an upcoming refresh of Apple’s MacBook and MacBook Pro notebook lines. These rumors were spurred by purported images which surfaced of a new bottom case for MacBook Pro’s which reflected some sleeker, MacBook Air inspired design curves as well as Apple’s own admission the other day of a “product refresh” later this year. Like many Mac heads, I’m rather excited about the prospects of the redesigned systems, and in addition to updating the system specs and adopting Intel’s new Centrino 3 “Montevino” architecture, I hope that above all, both models inherent design cues from the Air, and well as becoming lighter and slimmer. Furthermore, there has been a rumor in the last day or two claiming the new MacBook would gain a glass screen with iPhone-like multitouch, built-in GPS, and an accelerometer. This would also be neat! As I previously posted, there has also been rumor of an Apple netbook. Anyway, I decided to compile a short list of what I would like to see in the new models:

MacBook Air:

• Faster Processor – at least 2GHz
• 2 USB Ports
• Gigabit Ethernet Port
• Upgradable Memory (2 RAM slots supporting up to 4GB)
• Stereo Speakers
• Audio input (Mic in)
• Kensington Lock
• User-Replaceable Battery
• Upgraded iSight camera (the Air’s current version has less MP than other MacBooks and is fuzzy)
• Cheaper Price 

MacBook Pro:

• MacBook Air-inspired curves and design cues
• Lighter (5 pounds or less) and thinner
• eSATA Port
• Faster Centrino 3 Components
• Multitouch? 

MacBook:

• Faster Centrino 3 Components
• Aluminum Case (like MacBook Pro and MacBook Air, maybe even boring some design elements from the iMac’s rounded, aluminum sides– considering the iPods are all now aluminum – I really like the aluminum look, and it’s certainly more scratch/dirt repellent)
• LED Backlight Display
• Backlit Keyboard
• eSATA port; USB 3.0 (draft) – Not especially important, I’m just wishing here!
• Lighter (around 4-4.3 pounds – to compete with Windows competition)
• Thinner (to compete with Windows competition)
• Multitouch?
