Virtually all STM journals are now available online, and in many cases publishers and others have retrospectively digitised early hard copy material back to the first volumes. The proportion of electronic-only journal subscriptions has risen sharply, partly driven by adoption of discounted journal bundles. Consequently the vast majority of journal use takes place electronically, at least for research journals, with print editions providing some parallel access for some general journals, including society membership journals, and in some fields (e.g. humanities and some practitioner fields). The number of established research (i.e. non-practitioner) journals dropping their print editions looks likely to accelerate over the coming few years (page 30).

So Pharo is a like an easy transferable operating system moveable between systems and devices.
