OK, yeah, Google takes a bit of getting used to and OK, yeah it doesn't do absolutely everything that my old laptop did. But what I spend 99% of my time doing (email, meetings, notes, docs, presentations) it does it really fast.
Added to this all of the real time collaboration tools that just amazingly work really really well and I am totally converted.
A new idea.
I am in the business of making maps though so how do I survive? I have had to be inventive at times, this has even included me borrowing other's computers for their use of QGIS or setting a trial account of a legacy GIS vendor's online platform, but for the most part I have found I can enable my knowledge worker customers using Google Maps for business. All online, all through Chrome OS.
