I am considering upgrading to the Galaxy from my Tattoo. The app I currently use the most is Aldiko. The much bigger screen on the Galaxy appeals to me. I went into a shop the other day to try out the Galaxy and had a quick look at Aldiko which comes pre-installed on it. I have the latest version but the one on the Galaxy appears to be an old/different version and did not seem as good as the version I have. So my question is, can these pre-installed apps be completely removed (or upgraded from the market to the latest versions) or am I stuck with the pre-installed version forever (unless I root it). Thanks for any info.
