PC Advisor has announced that its Product Of The Year for 2009 is Microsoft's Windows 7 operating system.
Windows 7 was launched on October 22, 2009 - and has quickly moved to erase memories of Microsoft's loathed Windows Vista OS.
"Windows 7 is hardly flawless," PC Advisor editors wrote in their Windows 7 review. "Some features feel unfinished; others won't realize their potential without heavy lifting by third parties. And some long-standing annoyances remain intact. But overall, the final shipping version is the worthy successor to Windows XP that Vista never was."
PC Advisor editors and expert contributors had compiled a list of ten nominations for the 2009 Product Of The Year.
Alongside, Windows 7 were high-profile products such as Apple's iPhone 3GS ("You will not find a better internet-connected smartphone") and another Microsoft product, new search engine Bing ("it stands a chance of converting more than an impressionable few").
Other nominated products included the Flip MinoHD high-def mini camcorder ("a masterstroke of simplicity"), reported iPhone killer Palm Pre smartphone ("clean, engaging, eye-catching and intuitive") and Samsung N110 netbook ("record-breaking netbook battery performance").
Panasonic's Lumix DMC-GF1 was praised for creating a new category of digital camera - between the compact and digital SLR, using the new Micro FourThirds system.
At its sub-£200 price point the Sapphire Radeon HD 5850 was "the unbeatable graphics card of 2009".
PC Advisor will revealed its Product, Technology, Company and Person of the Decade (2000-2009) later today.
The PC Advisor Awards 2010 are sponsored by HP, AMD and PC Tools.
