I was thinking I might sit in the sun at Hyde Park (Sydney CBD, Australia) and answer my emails on wireless.
What Wi-Fi can I get? A quick search found a search tool for Skype that gives you a list of free or paid Wi-Fi points. Being a skeptic I tried it and it works really well. I even tried it in my home suburb and yep my local Starbucks is a go-er. Happy now 
You will need Skype to use it and then get the search tool at the JiWire Bot for Skype download page.
