My choice of other--explained here. Initially, my set-up was Kobo-->Kobo Mini-->Kobo Touch with Calibre running in Linux desktop. After 3rd Kobo broke and abandoned desktop, moved to Android + iPod Touch + Chromebook with Kobo app. The Android tablets not portable, bad battery life and iPod Touch battery died, 3rd party battery, then died again.Then decided wanted something fitting in pocket bought 2 Fire 7 tablets - cheaper than Kobo's, other Android or iPod Touch. Followed recipe to convert them to Android tablets, running Pocketbook app so DRM ePubs OK. Got used Windows laptop - stripped DRM from ePubs bought, set up Calibre. Moved to KOReader with syncing. Built up huge collection PDFs and djvu's with classical organization. Now running Calibre for ePubs only on Linux VM on Chromebook (Windows machine broken by Microsoft update).
