What is the difference between WiFi and wireless internet? I am interested in getting some equipment that is WiFi access only.

It's important to understand the difference between WiFi and wireless internet, especially if you are planning to buy a gadget to access the internet.
The iPad is a good example, as it is sold in two different versions. One supports Wi-Fi only and the other supports both mobile broadband (also known as wireless internet, or 3G) and Wi-Fi and is more expensive.
If you go for the WiFi only version, you will only be able to access the internet when you are within range of a WiFi signal. You can set up a WiFi network in your home, by using your existing ADSL1, ADSL2+, Naked DSL or cable broadband connection with a Wi-Fi modem.
Many cafes, libraries and public places, such as Federation Square in Melbourne, or the Manly Ferry in Sydney, also offer Wi-Fi services, so you can also access the internet while out and about on a Wi-Fi enabled device.
However, if you want an internet connection in more places, you will need to buy the mobile wireless (3G) version. Mobile wireless internet works over the mobile phone towers, so you don't have to find a Wi-Fi hotspot to use the internet, you can use it anywhere there is enough coverage.
You need to think about where you want to use the internet to decide between the two. If you want to use your iPad (or other device) on public transport, the chances are there won't be a Wi-Fi signal available, so you will need to buy the mobile wireless version and a mobile wireless plan.
For mobile broadband, you will need a modem and a plan. Some devices have a modem built in, so all you will need is a SIM card (or microSIM in the case of the iPad). If it doesn't have an in-built modem, you can buy one and plug it into the USB port on your device.
Mobile broadband providers like Optus (1300 768 194), Vodafone (1300 433 823), Virgin (1300 768 103), Telstra and iPrimus (1300 137 794) offer both pre-paid and post-paid plans that can be used on a range of gadgets, including the iPad.
