E6400: can anyone confirm that it can read Sony memory sticks

memory stick pro can't be read alone by any built-in card reader on laptops. it has to be inserted to a memory stick [regular] adaptor. i guess, only sony laptops has a stand alone memory stick reader.

in anycase, the only logical/practical choice you have is:
1] usb memory card reader for sony mem stick
2] nothing else.... the rest would be impractical

 

And remember not to buy sony cameras in the future... Making a mistake once is human, twice is dumb.
