Announced at the Macworld Conference & Expo on January 9th, 2006, the iPhone is Apple’s first foray into the cell phone market. The iPhone is a combination of a cell phone, iPod, PDA and a 2 mega pixel camera. The iPhone utilizes OS X as its operating system which uses a 3.5 inch touch screen for input. Two versions of the iPhone will be made available upon its launch, a 4 gigabyte version and an 8 gigabyte version, costing $499 and $599 respectively. Initially the phone will only be available for use through Cingular’s networks. A feature that the iPhone surprisingly lacks, but many other portable gadgets feature is a memory card expansion slot [Yahoo Answers]. Apple has had a tradition of not allowing users to upgrade existing devices with ease, this can be viewed as a practice of forcing people to continually purchase more Apple products as their need for memory and other features expand. This greed due to the constant upgrade cycle could have contributed quite a bit to Apple and its success. Another interesting issue with the iPhone is Apple barring the installation of 3rd party software on the iPhone. Why is this? It could be for many reasons. Apple implies that the unauthorized software installed on the iPhone could interfere with the operation of the device, Apple might also want to collect licensing fees for its software much like many Video Game console developers have been for years. Apple has also has had a bad reputation for the quality of products upon their release, often they are considered buggy and erroneous by users. Often many of the bugs are fixed in the future generation of the product. Apple may be waiting for future generations of the iPhone to come out before allowing 3rd party software onto the device till it is considered stable enough to run different types of software. The user interface of the iPhone is a new concept never been tried out in mobile devices before. The iPhones main input and control method is a 3.5 inch touch screen where you use your fingers instead of a stylus. This new control method might take some time to get used to for people who are used to dealing with stylus’s and thumb boards, this new control scheme might also be just a marketing trick, not really adding much to the experience of the iPhone. The touch screen might backfire on Apple if it does not prove easy enough to use. Much like its close relative, the iPod, the iPhone is expected to work like a mobile hard drive. The iPhone comes with either a 4 GB or 8 GB memory on board depending on the version you buy allowing users to store plenty of files including movies and music. Apple currently only controls a small portion of the Personal Computer market. The market is currently dominated by Microsoft’s Windows line of operating systems. Apple has converted many users with its new Intel processors used in its PC’s and the iPod and it may attempt to do the same with the iPhone. The iPhone may not work as well with Windows as it might with OS X. It may also have poor Syncing with Windows. Whether this helps Apple or hurts it is yet to be known, only time can tell on such matters.
