Here in Germany, buying a tablet with only wifi isn't wise. Up until recently wifi laws have been very strict. This is probably the reason why many Germans have tablets with LTE and probably the reason why Samsung chose Germany first to upgrade it's Tab S tablets with LTE.
The German government has cleared the way for open and private WiFi hotspots. A provider liability law that makes hotspot providers responsible for users' activity has long limited public WiFi and is set to be scrapped.
In a dispute over a new Telemedia Act, the German government agreed on Wednesday to relax the country's restrictive WiFi rules, which had previously left many German businesses unwilling to provide free Internet access to the public.
Private hotspot providers in Germany are liable for the misconduct of users. If, for example, a user were to download music or a movie on a particular hotspot, the provider ran the risk of being sued for piracy. As a result, public WiFi in Germany has long been hard to come by - much to the annoyance of the German public.
When and if the wifi only versions, worldwide, get the update depends on Samsung's willingness to support the Exynos chipsets. It doesn't look hopeful.
