Initial cost maybe cheaper but upgrading will be expensive IMO.
Nick White Blog:
"...that the Windows division has revised the retail license terms for Windows Vista in a significant way. Namely, the terms regarding license-to-device assignment of the retail product (including Home Basic, Home Premium, Business and Ultimate) now read as follows:
You may uninstall the software and install it on another device for your use. You may not do so to share this license between devices."
Retail license, no mention of the OEM license.http://windowsvistablog.com/blogs/windowsvista/archive/2006/11/02/news-revision-to-windows-vista-retail-licensing-terms.aspx
