Embarcadero / CodeGear has released RAD Studio 2009, which includes Delphi 2009, C++ Builder 2009 and Delphi Prism. Note that Prism has its own IDE, which is actually the Visual Studio shell; this is the new take on Delphi for .NET that targets Mono as well as Microsoft .NET. You can also install Prism into an existing Visual Studio installation.
Looking at the UK prices, RAD Studio starts at £979.00, whereas Delphi starts at £549.00. Upgrades are much cheaper – less than half the price in some cases. The message seems to be: get RAD Studio if you think you might need more than one of these three products.
I’ve been asked whether the upgrade to Delphi 2009 is worth it. I have no idea, of course, since it depends what you need it for – though if you need Unicode I’d have thought it was worth it for that alone. I do think it is the best so far in the post-Delphi 7 series. Personally I prefer it to Delphi 7 as well; though check Mason Wheeler’s comments to a previous post for a contrary view. Vista compatibility is another advantage, though you can hack this in any version of Delphi. I doubt that Windows 7 will be much problem here; it is close to enough to Vista that the same stuff should work fine.
