I forgot to mention that you don't necessarily have to install Ndless to play games or program more advanced programs. You can also write programs for the NSpire in Lua. Compared to the TI Basic this gives you more advanced options and full graphic capabilites, plus its much faster than TI Basic. There are quite some games out there written in Lua and also useful apps like for the periodic table of elements. Take a look at ticalc.org to get an overview.
