I can't speak for SeaKing, but a healthy dose of "common sense" helps here. Even though the tech industry is obsessed with convergence for decades, the "average joe" just wants a gadget that does the job well. That's why ereaders are popular. That's why TVs refuse to die a graceful (and prompt) death. That's why portable music players still exist in a world where the ubiquitous cell phone could happily complete the task. And need I mention the handy calculator? Those simpleminded critters quite often sit next to computers that are powerful enough to do the maths for sophisticated 3-D animation, complex data analysis, and mind boggling modelling for science and engineering.

I've been interested in computers for long enough to remember the days when convergence was virtually promoted as, "the best way to create a $200 sound system is to buy a $2000 computer". Because of that extended history with technology, I'm fairly confident in predicting that the eink ereader will outlast the general purpose tablet. It will do so simply because it provides people with what they want in a package that they can understand. That isn't to say that tablets are going to disappear anytime soon or that eink ereaders are going to stay the same. But general purpose computers have changed a heck of a lot more than the dedicated devices that they were supposed to replace. Since tablets are almost general purpose computers, they are bound to transform beyond recognition before eink readers vanish from the marketplace.
