Only really old ebook readers (e.g. Sony PRS-500) will have any problems with more than 300KB per file. |
Actually, the PRS-300 and the PRS-x50 series suffered the same. My PRS-T1 does open bigger files, but will get slower near the end of the file. At one time turning a page took almost two seconds. That file was around 600 KB I believe. So, it is mainly for older devices, but newer devices (not that I consider the PRS-T1 'newer') can become slower. This is probably especially true for e-ink devices which are usually not that generous memory and CPU wise.
