For some the lack of a spell check could be a problem although you can get a limited functionality in this area by using a third party app. Mostly though because my wireless broadband is so unreliable here I tend to type my replies into PolyEdit and then just copy onto the site, otherwise I can be half way through a long reply and lose it all
