A client asked me today why our CMS rich text editor does not work in the iPad. After a bit of digging around, it seems that the contentEditable property in the ipad's safari based browser is not supported. Therefore, no browser based rich text editor will work on the iPad. Suggested alternatives include using a plain text box (not ideal for using rich html content) or creating a custom app for the CMS - I don't really have 6 months spare to rebuild the whole CMS as an iphone app.

The second generation iPad, iPad2 is rumoured to be released in Feb 2011. Details are sketchy, but there is little to suggest the the wysiwyg editors will work in that either. The windows 7 based tablets will support the contentEditable property. I've not got a definitive answer on whether android (or chrome OS) tablets will support the rich text edtiors.
