… about the current state of the Personal Computer business, Hal Berenson has already said better.
What I would like to add is that probably not only consumers will abandon the PC, but enterprises will too, eventually.
Already today a lot of hip (or cheap) companies pursue BYOD and if those devices are tablets (or similar kinds of usage-restricted Internet terminals), so be it and they will have to adopt to it.
Apple, Google, Amazon, and eventually Microsoft, will learn to blend their marketplace story into the enterprise, as providers of out-sourced software delivery, if you will.
Finally, at least somebody with some sense of quality might bring sanity into the world of corporate software development.
