Coming back to the present state of affairs, you need to realise that ereader hardware architecture is a) underpowered in many ways because of two requirements - battery must last weeks, not hours; b) thickness and weight of the system must be very small. Which in turns means that the heat emission from mainboard must be almost null. Hence computational power is limited.
Last but not least, core function of reading (reading app at the high level and driving e-ink screen on the low level) is computationally very much resource consuming. Keep in mind that this function must deliver reasonably short wait times while redrawing pages, even if processor is operating only at 800 Mhz max.

None of that has the slightest bearing on the feasibility of switching between two open books. The current crop of ereaders have plenty of resources to do just that without overheating or running the battery down.
The "Tales about IT 20 years ago" was an illustration that much more demanding tasks were performed with much less capable hardware 20 years ago. Size, power, and heat are constraints, but they come nowhere close to preventing switching between books on the current crop of readers.
