According to Pfeiffer Consulting people's productvity on PCs with Windows Vista is lower than Windows XP SP2 or Mac OS X.
Their conclusion is backed with cold, hard research. Pfeiffer Consulting conducted the research based on an independently financed series of benchmarks that establish how Vista impacts User Interface Friction (UIF) and user efficiency.
Pfeiffer Consulting, a Paris/France based international research and consulting operation specialised in technology and media, just recently released a report on Windows Vista User Interface Friction (UIF). UIF is a Pfeiffer concept, which describes and quantifies the perceived differences in efficiency and user experience between operating system, applications, and digital devices. UIF defines the fluidity and productivity that can be observed when performing the same operation on different computer systems, programs or devices.
The benchmarks run on Vista’s performance were a selection of what Pfeiffer can measure. The results of this new report are therefore nowhere near a complete assessment of the Windows Vista environment where it matters for creative professionals. The first benchmark Pfeiffer measured is Mouse Precision Mouse precision is essential for those who use the mouse to accurately position elements: CAD, graphic design, page layout, web design, etc.
