While Microsoft is to make its Vista and Office 2007products available for Internet purchase and download in north America, the rest of the world – including South Africa – won't have that option. 

Reports suggest that the software giant is experimenting with new software distribution methods and only expects minimum uptake of the option. It has restricted downloads to its north American region.
South Africa, of course, is a different kettle of fish with its severe bandwidth restrictions.
Last year, Microsoft SA itself could not download beta versions of Vista from Redmond.
At a press conference late last year to announce the 30 January commercial launch date for Vista, Jonathan Hatchuel, Vista Business group executive, admitted that the company had experienced download problems and confirmed that the products would be shipped in Microsoft's more traditional manner – on disc or pre-loaded with an activation key.
