I desire to have an internet connection for my personal computer and i would like to know whether broadband or wireless is the best to get speed at affordable cost.
When you buy broadband from an ISP you will most likely get a wireless router that you can connect to wirelessly, unless your question was broadband or 3g, which my answer would be get broadband.
Whichever you choose make sure you avoid a capped service, such as one offered by an ISP called Smart Telecom out of Dublin. There are far better ISP's offering far better uncapped higher speed deals.
