Quoted from Casadellibro.com, in reference to the Tagus Lux ereader (firefly clone):
"Compatibilidad de formatos:
El eReader Tagus Lux es compatible con formatos de contenidos incluidos PDF&EPUB DRM, TXT, HTML, CHM, PDB, MOBIPOCKET, FB2, DJVU, PDF, EPUB, WORD, PPT, EXCEL (2007&2003), MP3, RTF, ZIP & RAR etc."
No translation needed. It supports PDF & EPUB protected with DRM... AND PDF & EPUB... the latter being any
PDF and any
...so, this comment by Booxtor on the Tagus Lux is just not true:
"The selling model is similar to Amazon - you will be able to use content of the seller only. This is why those devices are slightly cheaper than ours."
