If you're using Delphi Professional or C++Builder Professional and don't have XE5 with the Mobile Add-On Pack yet, there is a great limited time offer to get you to XE5 with mobile.
50% off Mobile Add-On Packs for Delphi XE5 Pro and C++Builder XE5 Pro
Add mobile development to your XE5 Professional edition IDE and expand your app development beyond the desktop to iOS (for Delphi and C++Builder) and Android (for Delphi). Now you can use your favorite desktop application development tool to create mobile apps too!
As you can guess by the name, the Mobile Add-On Packs require either Delphi XE5 Professional or C++Builder XE5 Professional.
Considering a different edition? Delphi and C++Builder Ent/Ult/Arch editions and all editions of RAD Studio XE5 include mobile capabilities with no add-on pack needed. Special limited time offers are available on those product editions including free additional software and the Coding in Delphi ebook by Nick Hodges.
