Mobility distribution has been swallowed by Java distribution. What a nice title for a newspaper. But the reality is simpler. NetBeans
just changed the distributions that are provided for download for users.
There used to be Java SE, Java EE, Mobility (Java ME) distributions in old releases. In NetBeans
6.5, there is only small Java SE distro and big Java bundle that includes everything about Java development including Java ME, Java SE and Java EE + the server side.
Picture is worth a thousand words:
NetBeans 6.0 distributions
NetBeans 6.5 distributions
If the bandwidth is problem for you and you want to download as less as possible then you can download the Java SE distribution. Later when you need an additional functionality just open "Tools > Plugins". You can choose what plugin or whole category of plugins you've missed and install it.
