"Windows 7 feels faster than Windows XP and Vista, but it turns out that's not always the case--sometimes, it's the slowest out of the three operating systems," reports CNET. "As you can see in the chart, we found that Windows 7 RTM was the fastest to shutdown, and was tied with XP for iTunes encoding. However, it was slower than XP and Vista for both booting up cold by a bit more than 1 second, and slower than either of its predecessors in its Microsoft Office performance."
Compatibility with old software and hardware
Engadget maintains a Windows 7 upgrade guide, but in their review they say that "anything we found to work in Vista seemed to work just fine (in some cases better!) in Windows 7. That goes for hardware and software, but of course the real test will be when this OS is unleashed upon the masses -- your mom's brother's 25 year old printer might not make the cut, and we'll be sure to pour out a 40 upon its behalf. In truth, Microsoft does a very good job with keeping a truly insane quantity of hardware and drivers and vendors happy, but we still think they could do better."
