Being locked into the cloud
At work EVERYTHING I do is cloud based from my desktop. When I'm on the road at customer sites, EVERYTHING I do is cloud based from my notebook, tethered to my phone. In such cases, as the author has also described, cloud computing usually offers everything you need. Document sharing (Pricing, brochures, quotes and invoices), web browsing, access to company 'cloud based' CRM, cloud printing etc.
If you need a personal notebook, for running your own software choices locally, editing graphics, video, audio, playing games, storing a lot of files and data etc. A Chromebook is not designed for your needs at all and doesn't claim to be.
For work I run a Dell (blech), it has a tiny SSD (128GB) but is rocket fast for work computing needs. Intended use is exactly the same as a Chromebook and it certainly lives up to cloud based work needs.
