TweakTown writes data from Soluto's online database of PC crashes shows the 13" Retina MacBook Pro from Apple with Boot Camp installed is the most reliable "Windows notebook" you can buy:
Soluto used "data from its massive online database of PC crashes, hangs, and performance metrics to identify the 10 most reliable Windows PCs you can buy today". Their study found that the 13-inch Retina MacBook Pro with Boot Camp installed is "at the top of the list". Their study found a few other suitable candidates, the Dell Vostro 3560, the Dell XPS 13, Acer's Aspire E1-571, Acer's Aspire V3-771 and Apple's 15-inch Retina MacBook Pro.
When it is all swirled together, Apple computers make up 33% of the six most reliable Windows PCs in the world.
