And, of course, consider your budget, your level of comfort with computer and web technology and how much effort you're willing to put into getting the best out of the package you choose. Take time to think about how you like to work - consider what's been right for you in other circumstances (work, education, other hobbies) and take advice from the experts on what you'll want in the future even if you don't realise it now. The important thing is not to select it on the basis of a single feature now, when (with luck) you'll be using it for years to come and your requirements will change and mature.
