Many of the basic specs of the MacBook remained unchanged over the four years it was produced. The first MacBook was 13 inches (33 centimeters) wide, had a 1280 x 800 resolution screen, sported a plastic (polycarbonate) body and was available in two colors: black and white. The final 2010 version also had those same specs. The only major body change came in 2008, when the aluminum unibody model was released. However, in 2009 the aluminum unibody version was rebranded as the 13-inch MacBook Pro [source: Apple].
The internal hardware, on the other hand, was upgraded over time. In May of 2006 there were three versions of the MacBook available. The first had a 1.83 GHz Core Duo processor and a 60 GB hard drive. The second two were slightly more powerful, with a 2.0 GHz processor and an 80 GB hard drive. All three versions had 512 MB of memory. In mid-July, however, Intel unveiled its new Core 2 Duo processor, and the November 2006 MacBook offerings reflected that change. All three released that month sported the new Core 2 Duo processor (in 1.83 and 2.0 GHz). Another big change by the end of 2006 was that the top tier MacBook now had a 120 GB hard drive and 1 GB of memory -- twice as much storage space as its first tier model [source: EveryMac].
Over the next four years all specs on the MacBook continued to improve. By the time the computer was phased out in 2010, the offerings had increased tremendously -- a 2.4 GHz processor, a 250 GB hard drive and 2 GB of memory -- not far from what the 13-inch MacBook Pro was offering at the time.
The MacBook also featured a touchpad (or trackpad) mouse that sat right in front of the keyboard and a built-in camera right above the monitor. The 2006 model could get 6 hours of battery life from its lithium-polymer battery, and by 2010 the battery could last for 10 hours. The MacBook also had several ports to allow you to hook up with other devices. All versions of the MacBook featured an Ethernet port, two USB ports, a mini DisplayPort (to connect to a TV or computer monitor), a FireWire port (to hook into a computer network) and a DVD drive. Some early versions had separate in and out audio ports, but the later versions combined these into one [sources: Apple, Apple].
