This article gives a few good reasons to migrate, along with an overview of the most important features added to Delphi product releases since version 7. If you already read my article “Reasons to migrate from Delphi 7 to Delphi 2009”, this article include updates related with Delphi 2010 and XE.
We understand that developers are busy creating software, and that spending time to migrate to a new version is not always possible since you always have to deliver new projects.
Possibly the best reason for you to migrate to Delphi XE, C++Builder XE or RAD Studio XE, is that buying those versions gets you earlier versions at no extra cost. For example buying Delphi XE also gets you Delphi 7, Delphi 2007, Delphi 2009 and Delphi 2010.
I hope this article answer all of your question, any additional question let us know how.
