maybe.... we all hope so!
nevermind about the different versions of Vista:
Windows Vista Starter
Much like the Windows XP Starter Edition, this edition will be limited to emerging markets, mainly to offer a legal alternative to using unauthorized copies. It will be severely limited, for example only allowing a user to launch at most three applications with a user interface at once, will not accept incoming network connections, and physical memory is limited to 256 MB.
Windows Vista Home Basic
Similar to Windows XP Home Edition, Home Basic is intended for budget users not requiring advanced media support for home use. The "Aero Glass" theme with translucent effects will not be included with this edition. Home Basic will support up to 8 GB of physical memory.
Windows Vista Home Premium
Based on the Windows Vista Home Basic, this edition will additionally support more advanced features aimed for the home market segment, such as HDTV support and DVD authoring. Extra games, mobile and tablet computer support, file system encryption, and a photo management application are also included. This edition is comparable to Windows XP Media Center Edition and Tablet PC Edition. Home Premium will support up to 16 GB of physical memory.
Windows Vista Business
Comparable to Windows XP Professional, and aimed at the business market. Does not include the Media Center features of Home Premium, but does include the IIS web server, fax support, offline files, dual physical processor support, Remote Desktop, ad-hoc P2P collaboration capabilities, and support for 128 GB of memory. Product activation is not present in this edition.
Windows Vista Enterprise
This edition is aimed at the enterprise segment of the market, and is a superset of the Business edition. Additional features include a single-session version of Virtual PC, multilingual user interface support, BitLocker Drive Encryption, and UNIX application support. This edition will not be available through retail or OEM channels.
Windows Vista Ultimate
This edition combines all the features of Home Premium and Enterprise editions, and additionally comes with podcast creation support which Microsoft has dubbed "blogcasting" a game performance tweaker (code-named WinSAT), DVD ripping capabilities, and special online services for downloadable media, as well as additional customer service options. The Ultimate edition is aimed to be the most impressive edition of Vista, aimed at high-end PC users, gamers, multimedia professionals, and PC enthusiasts. Like the Business and Enterprise versions, product activation will not be required.
