Toronto Public Library supports Overdrive and with the newer Kobos you can check out books entirely from the device. You can also still sideload them with Adobe Digital Editions if you were doing that for your Sony.
They can read ePubs from other stores so long as they are DRM free or sideloaded with ADE.
EDIT: They do have foreign language dictionaries you can download for free, most of the bigger languages are covered well like French, Spanish etc. Something like Welsh though you'd have to add it yourself.
