I researched chromebooks for months before making my purchase and am so glad I did.  Others may have differing criteria and parameters than mine, but here's the breakdown of my research and why I chose this HP X360 12" model:it was a 2-in-1 laptop/tablet with a chrome OS (I had no need for full functionality of laptops with Microsoft OS, so why pay more for it?  Plus for me, chrome is much easier to use.)It was small and lightweight, making it more manageable when in tablet mode.The aspect ratio of 3:2 vs the more standard 16:9 is OUTSTANDING for my purposes, being web browsing, email, documents, etc.  I rarely stream videos, which is the only drawback of the 3:2, since videos are in 16:9, but even when I do, I don't at all mind the upper and lower bordering.  Plus the 3:2 allows for a larger screen in a smaller overall sized device, which to me is much more practical.  DEFINITE a plus in my book!!By process of elimination, I chose an HP product for the following reasons:My research revealed a lot of disgruntled customers of Lenova products in regard to warranty issues and customer service.The smaller model chromebooks, of which I was researching were not equipt with C-type USB ports in the Acer models and ONLY equipt with C-type USB ports with Asus models.  I wanted at least one of each type, C and A.And Dell had little to offer in the small chromebook market.That left HP, of which my family has owned many different devices over the years and with which has had no issues, so I was happy to own another HP product.In regard to performance, it was extremely easy to set up and get going.  Chrome OS stepped me through all the settings, and personalization.  It took no time at all.  I've been using it daily for weeks, and have had no issues with speed or any other performance criteria.Overall, I would say the main selling feature for me with this model, beyond being an HP, was the 3:2 aspect ratio.  I LOVE it!  I highly recommend this HP X360 12" chromebook!!
