I'd prefer to call it a "Multi-Readia " device; that is an e-reader with other media capabilities. It handles text, html and RTF files adequately though PDF's can be difficult to view. Results on mine have not been consistent. On some PDF files its fine and on some not quite up to scratch.But this may be due how and what application was used to encode the PDF initially.
It plays film also -, rather well in fact. It plays back MP4, AVI, MKV,FLV,VOB,DAT,RM,RMVB,MPEG2 and DivX according to the manual. I have personally tried MP4,DivX and FLV files and they all playback without issue and quite smoothly. Incidently, the Sovos SVEBK5 has a Rockchip chipset RK2800 which makes an appearance in many Chinese made multimedia players and does the job of playing multimedia files quite well.
For music it plays it supports MP3,WMA, WAV and OGG. Quite impressive for a device which is marketed primarily as an e-reader.
It is a drag-and-drop affair and no particular file management application is required (unlike a certain vastly more expensive 10" closed device that has captured everybody's imagination)and it has an SD card supporting up to 8GB storage.
Lastly it works on non-MS Windows operating systems such as Linux and FreeBSD as it mounts likes a standard USB flash drive. You'll also see the SD card appear likewise if inserted. In all it works well for what it does and visibility is good. It user interface is not pretty or flashy but is easy to navigate.
