For the first time in my professional life, I have a ‘work’ iPhone. For many years, I have simply relied on my personal cell phone to assist my professional life, but I am finally in a position where my employer has provided a work phone for my use. As a rule, I strive to keep my work life and professional life separate. I feel this is important especially in the position I am in now where it’s possible for work colleagues to need to contact me on my off hours.

The main reason I decided to share this with the viewing audience is because the work phone is an iPhone 4 and my personal phone is an iPhone 5. Now, my iPhone history goes like this. I purchased the original not too long after its release. Unfortunately, it met with an untimely death when I dropped it and the power button was smashed in. At the time, I decided not to replace it with another iPhone (mistake), and instead got a flip phone. Just before the iPhone 4 dropped, the price on the 3GS also dropped and I took the opportunity to acquire the iPhone again. Then, just a few short months ago, my boyfriend surprised me with an iPhone 4S as a birthday present. When the iPhone 5 was released, we upgraded our respective 4Ss and now, I also have an iPhone 4.

It’s an interesting experience having two iPhones side-by-side to compare at the same time. Since my hand is so used to the iPhone 5 now, it was quite a weight difference holding the iPhone 4. The 4 weighs in at 4.8 ounces while the 5 weighs 3.95 – almost one full ounce less. You wouldn’t think that would be enough to notice, but it is.

Secondly, the size of the phone jumped out at me. The 5 is quite a bit thinner and of course, it is longer, too. It is a noticeable difference when your hand wraps around both phones. To me, it’s almost the same type of comparison as the iPad is to the iPad Mini.

Finally, I find the screen size to surprise me every time I use the 4. I’m so used to the 4-inch screen of the 5 that the half-inch difference on the 4 really jumps out at me.

The iPhone 4 is a good phone and I’m grateful to have it to take the professional burden off of my personal phone, but I am really glad to have the iPhone 5 as my primary phone.
