Easy to use, good support for web development, easy access to documents via Sharepoint. It's also possible to write code in C# or VB and work with ASP Server side programming if required. The main problem that we have at our organisation was the slow page loads from our intranet site. This has now been solved by using A2K services as this speeds up loading pages considerably (page load times reduced by almost 50%).
I like it that you can access from anywhere at anytime,it's easy to use evenβ¦
