Nokia 7900 Prism
One of the first Nokia devices with the breakthrough 'prism' design, the Nokia 7900 Prism led to a range of devices following the same triangular pattern. The device range was not a major hit among consumers but they were innovative and inventive in their aesthetics ideals.
Released just before Christmas 2007, the striking feature was the device's keypad design, which also allowed users to change the keypad's backlight color. It included 2.5G EDGE speeds for faster WAP browsing, and the color screen boasted a 200 pixel-per-inch (ppi) density allowing for a sharper image. Strangely, the top of the device was completely flat -- quite an ugly 'ending' to the device -- that made marketing the product tricky. It does, in fact, look as though the top of the phone was sliced off through an over-zealous image cropping exercise.
Nokia 7070 Prism
Released in 2008, the Nokia 7070 Prism was a design feat over anything else. Stuck on the 2G GPRS network, its main feature was a jagged, prism-like design on its outer casing and a similar designed yet standard layout keypad. The flip phone was simple: it didn't include a 3.5mm headphone jack nor did it include a USB port unlike many other Nokia phones at the time. This was, however, before Nokia signed an agreement to partner with other phone makers to include the micro-USB port as part of a wider European Union push for device charging standards.
Another daring design for Nokia, this fashionista's phone was one of the first devices on the market that had no dialing pad. It didn't even have a touch-screen display, so how would it work? Through sheer hard work, most users found.
On the market in 2004, the thin-film transistor (TFT) screen with 65,000 colors may have had a thin and bright, colorful display, a slim and sleek design, and a VGA camera -- which was rare for the time -- it had to be operated by an iPod-like wheel. But it wasn't touch-sensitive; one physically had to spin the navigation dial which resulted in sore thumbs. Just imagine sending a text message by having to scroll through each and every letter; it's hard work and the phone barely took off.
