First three definitions I could find - none of which would cover the Apple Apps.
http://www.urbandictionary.com/define.php?term=bloatware
A piece of software, hardware or website that attempts to do too much and becomes utterly useless for users. An example of bloatware would be a word processing application that also tries to be your page layout program, drawing tool, and web browser; absorbing half your hard drive and all your RAM in the process.

1) Applications that are overloaded with features. See software bloat and wares.
(2) Myriad applications pre-installed on a PC by the vendor. Many PC manufacturers are paid by software vendors to pre-install lite versions of their products on the PCs they sell. In addition, some of these applications load at startup, wasting memory and providing a potential for conflict with other applications. For a fee, some retailers offer to rid the new PC of bloatware for their customers.

Bloatware is software that has unnecessary features that use large amounts of memory and RAM. Software comes to be known as bloatware when it becomes so unwieldy that its functionality is drowned out by its useless features. This is also known as software bloat.
Bloatware is also a slang term for numerous programs that are pre-installed on new PCs. Many of these programs are "lite" or limited trial versions designed to entice new users to buy or subscribe to the full-featured versions.
