We are mobile devices.

I tend to have a better specification than a laptop, I often cost less BUT I am not mobile.

I can use WiFi and 3G/4G without the need for an adapter.

We do not need a constant power supply.

I am a large powerful computer that other machines attach to. I can share data and programs with other machines/devices.

I am ideal for sending emails, browsing the Internet and streaming video content on the go.

I need a constant power supply and I am not portable.

We have built in front and back cameras that are great for taking images and making video calls.

I link to a smart phone using Bluetooth and I am wearable technology.

Facetime and Skype are examples of VoiP?

Compared to a desktop PC, we are not very good to use when creating presentations, documents or websites.
