The ease of use for creating dynamic websites, cross-browser compatibility with HTML5 standards (HTML/CSS), WYSIWG editor which can be used very easily without any coding knowledge etc., dojox widget library has all kind widgets available in it like tables, charts & graphsetc..The best part about this product would definitely have been its price range compared other products out there at their respective places! Nothing much as such but I think if you're looking into something free then go ahead because everything else will cost some bucks so no point regretting later after spending your hard earned money!! Developing custom applications using JSPs for our website development project needs or developing small scale projects by myself when my team doesn't require too many fancy features from me :).
