I find (using the wonderful little app DiskUsage) that some linked
apps still use the internal memory for data that they cache.
Google Currents was the worst offender (a varying difference of approximately 50 megs in the internal storage
when I install/uninstall), so I have uninstalled it, but have it backed up. This is on the off-chance that its data storage, is in the future, given the option to choose the SD card instead.
Maybe I shouldn't be linking all the files (exclude the cache linking option for these apps in Link2sd?) of these apps. Any further advice on that would be great!
I tried hard to find the answer elsewhere. I'll experiment in the meantime, as I do like Currents!
I would tolerate the Maps usage as for me it can be crucial information needed in low data coverage areas ...
