gps apps take up a LOT of space. the 2 i installed. are 2 gigs A PEACE.
they are full fledge apps. not internet required apps.
In your two posts above you imply that 4GB uses most of 12GB. When you buy a 16GB device, you are really buying one that has approximately 12GB free for user data. The two GPS apps you note as using a total of 4GB combined use only about a third of that available 12GB amount. That leaves approximately 8GB free, which means that nearly 66% of the total available user space remains available.
Most apps don't use that much space. I count about 160 apps installed on my tablet with total internal storage use by the apps being less than 800MB. If you were to add that amount to your usage, then you would still have 50% free.
My other storage use is all in the form of files that I can move to external SD or USB storage as needed.
Everyone has different usage habits though, so your storage needs may be higher for any number of perfectly good reasons. The point of my previous post was (and is) that if you want more free space, you can probably clean up the storage to remove waste and get more actual value from what you purchased, and possibly reduce the need for more drastic solutions.
If you are using the internal GPS with ICS 4.0.3, and you have not cleaned up the files that are being leaked into /data/gps, then you probably have a significant amount of space wasted on your device. It seems likely that you are using the GPS because you stated that you have at least two GPS apps installed. If you clean up the waste, and then still run short of free space, and do not wish to reduce the amount of installed apps or data on the device, then you can either buy a device with more internal storage, or look over at xda at this procedure for increasing internal storage by mounting a 32GB external SD card on /data/media:
