There are a lot of free apps to view the current weather. This app can give me the weather of a place that is more than 100 kms away and I can upgrade to view the weather of a closer location... No, thanks.

The classic iWindsurf layout on the website is much better. For example, there is an alphabetical list of all my favorite sites on the left side of My iW page. Also the list of windy sites on that page is more compact with a horizontal bar to represent the wind speed. On the page for each site I can click a link to see the map of the surrounding area and I can jump to a nearby site from the drop down list. etc.

In this area (Columbia River gorge) I consider iwindsurf a must-have accessory for serious wind sports addicts. This is due to the pro forecasts as well as the proprietary live wind sensors.
