You can control every aspect of the product only with three keys, Up - Menu - Down so there is absolutely no problem to learn. It is charged through the USB connector (it does not include a cable but a USB connector) and you can upload pictures through this port as well with an application called DPFMate, which is included once you connect the Photo frame to the USB port, no CD needed.
There is no problem with Windows (fully compatible) and if you have the autorun feature enabled, the application is launched automatically, select the picture (one by one), crop them if you needed and download to memory.
There is only two options for displaying pictures, automatic slide show and manual. Sorry, no random feature. I recommended for the price. Thank you.
