How old are those computers? I have never seen those in my life! I am so glad Apple has renovated their designs! Wow! The simple white or silver laptops, desktops are the best choice! If I have any object that is loud with color or designs, I get sick of it very quickly.
Here's a brief history of Apple styling:
The 1980s into the early 90s used the "Snow White" design language, which was boxy white or gray with parallel lines molded in.
The 90s saw beige boxes, although they tended to be more "curvy" than competing PCs.
The return of Steve Jobs brought the "funky color" and crazy design era of the late 90s. He also simplified the product line-up to the "four box" model, with both a desktop and a portable in both the professional and consumer categories. The first product was the iMac, which originally came in "Bondi Blue"(a sort of dark green-teal color) but was later made available in other colors. You also had the clamshell iBooks, which also came in a variety of colors. The professional desktop was the Blue and White G3, which had front and side panels about the same color as Bondi Blue iMac and white frosted, translucent side panels. The only "conservative" option Apple still had was the Powerbook, which was black but a lot more "curvy" than the competing products and had the glowing Apple on the lid(albeit upside down).
The early 2000s saw the Clamshell iBook replaced by "Snow" iBooks which had more or less the same overall design as the white MacBooks that were made up until a few years ago. The iMac G4 was an amazing piece of engineering, with a white "dome" housing the computer and an LCD panel on an articulated arm so that the screen could be positioned anywhere. The professional towers kept the same basic layout but had the coloring toned down to a more conservative "graphite" scheme with dark blue front and top panels, and light gray opaque side panels. The professional laptop became the Titanium Powerbook G4, which had a silver gray titanium lid and bottom panel wrapped around a gray plastic main body. You also had the Cube, which IMO is one of the most gorgeous Apple products of all time. The professional G4 towers kept the same basic exterior case, but went through a couple of coloring and other design changes-the Quicksilver, which was plastic-silver all over, and then the Mirrored Drive Door, which has two optical drive doors covered by mirrored panels.
2003 brought a couple of dramatic changes. The professional desktop became the PowerMac G5, which introduced the basic "cheesegrater" aluminum case that was used(with some modifcation) for the Mac Pro through 2013. As a complement to that, the Powerbook G4 was completely redesigned in Aluminum and now in three sizes(12", 15" and 17"). The basic design of these(less the 12") carried over to the Intel era and lasted until the Unibody Macbook Pros came out in late 2008. The Imac G5 was in an upright white polycarbonate case, which lasted well into the Intel era when it was replaced by the aluminum iMac in 2007.
Aside from the Mac Pro, the last major design changes were in the 2007/2008 era, when the iMac and Unibody Macbook Pro were introduced. Subsequent changes have made products thinner and lighter, but kept the same overall look and feel of the products introduced in those years. Of course, the new Retina Macbook is a pretty radical departure as well.
