This is a parents view, as my son is getting this for Xmas. I have however done alot of playing and setting up the device ready.
It uses motion and touch for all the games and apps, like a phone does. As every game as motion built in, in some way, this is the part I feel my son will love the most (he also has a leappad, but not much motion on them yet).
The cartridge games have a ebook included and 5 games / creative apps which are all character based.
Downloadable apps are also available to download for a small cost although the current libarary isnt alot.
If you install a SD card (I currently have a 4gb in for testing purpose) you can download movies of your own choice for free, music, photos etc... I have currently added 3 full length Disney movies, 5 peppa pig episodes, 5 fireman sam episodes and 2 other smaller cartoon movies. I have put on 3 music albums and also lots of family photos (taken from my 12m camera) and I still have over 2gb left.
I love the colour and pop app, which is a colouring book app (leappad lacks this) and once you have coloured your picture you can move it around and take a photo off it.
Although there isnt a camera, some apps allow you to take virtual photos. You can move around a picture to take a "photo" of the things you want.
Calendar app, notepad app, stopwatch, calculator and address book are all added extras, which my 4 year old wont understand at the moment, but will be a great added bonus when he is old enough.
It comes preinstalled with a ebook, 2 games and you get 3 vcoins to download 3 of your choice.
