Upgrade pricing for Delphi 2006 and Borland Developer Studio 2006 (BDS 2006) users is only available until December 31, 2010. If you're still using version 2006, this is your last chance to get upgrade pricing to Delphi XE, C++Builder XE or RAD Studio XE.
Starting January 1, 2011, registered 2006 users who haven't purchased a later version will have to pay the full new user price to move to version XE or any newer version in the future.
Now is the best time to upgrade to get upgrade pricing before time runs out and get the bonus of an extra tool free with the Buy One Tool, Get Another Tool Free promotion that also ends December 31st. Check out the Embarcadero "Where to Buy" page for all your choices for buying Delphi XE, C++Builder XE and RAD Studio XE.
