We just received a Vtech Bugsby reading system for our 4 year old. The system is easy enough to use. Just place a small cartridge in the pen and turn the unit on and run it across the words or pictures and out comes a mechanical voice. The kids think its fun to hear the words they see turn into sounds. My 8 year likes to play with it even though she's a proficient reader. The only issues we have encountered so far is that my 4 year old has some issues going in a straight line so he tends to "read" sentences above and below the one he intends to. The buttons on the pen are also somewhat tiny so may be difficult to press but I suppose it may be that way to avoid accidentally pressing it while holding the pen. The books can be a little pricey , especially if you pay full retail price for them. Overall, I think this would be a fun way to get young kids interested in reading and give them a sense of independence regarding books.
