Actually, it is crapware, at least as I see it. I have no use for social media sites and I'm not a 13 year old girl, so I'm never going to use anything named "Hangouts". If I have to have it installed on my device and I'm never going to use it then it is crapware.
Ok so you don't like social apps. Now tell me how you feel about having a market place for apps, a keyboard, the system level text-to-speech interface, google maps, a browser, a print service, an easy to access search function, ... the list of Google apps that are almost necessary to the Android experience goes on yet people keep using the word crapware. I wonder what my computer would be like if I installed an OS which had no browser or ability to print.
But it is worse than the crapware installed on a laptop. While the manufacturers think nothing of selling a laptop with an undersized hard disk ad then filling that disk space with crapware, at least I can uninstall the crapware on a laptop and recover the space. On Android, by Google's own design, you can't simply uninstall the crap that has been pre-loaded on your tablet. Significant amounts of very limited flash memory
You had me until you said Significant amounts of very limited flash memory. Google's complete app package takes up a pittance of the total OS even including those features required on a system level like a text-to-speech engine and a keyboard.
The reason you can't uninstall them is the same reason your laptop which allows you to delete everything will come with a multi-gigabyte large recovery partition hidden from the OS. The default apps are read-only to facilitate a factory reset. Nothing more. Don't like the apps? Hide them. If you seriously have problems with storage space then maybe you should spend more than $50 on your next Android phone, or get one with an SDcard slot.
