Think about Wi-Fi connectivity
One of the last choices to make is whether you choose a model that only offers Wi-Fi connectivity, or one that also features mobile 3G data, like that on a mobile phone.
If you're only planning on using your tablet at home or work, then a Wi-Fi model is your best bet, as it will keep the costs down.
If you're planning on using your tablet on the go, whether for work or play, 3G will ensure you will always have access to the internet.
While Apple's iPhone and some Android phones will allow you to create a personal Wi-Fi hotspot that you could connect your tablet to, bear in mind that this could push you over your mobile phone's data allowance, so a dedicated 3G plan for your tablet would be the ideal solution.
