Starting over: Here's the memory usage of scalc, w/ a fairly large multi-sheet excell spreadsheet running on ATOM netbook w/ Fedora 15/x86_64. *

Now, even when using 64bit libraries and binaries 112MB *should* be suitable for any modern portable device (my SGS2 now has ~500MB of *free* space), but once optimized (E.g. using 32bit libraries instead of 64bit - something that will lower the resident and virtual memory size by a factor of ~2), it should be usable on any low-to-mid-end smartphone.

No way am I going to allow a single program on my phone to use 112 mb. It would be slow, and not allow me to task switch or anything else very well.

Having said that, I think there is a huge market for decent office software on phones but they need to make it optimized for the form factor while leaving most of the functionality.

Keep in mind that I'm running 64bit libreoffice running on a 64bit Linux - actual memory usage on a 32bit android smartphone should be considerably lower - well within the limits set by mobile browser (around 60mb)

112MB on a phone is way too much. I don't really care if it's open source or not as long as it works, it is functional and it is efficient.

"...late 2012 or early 2013..."

Are you certain mobile devices won't advance in the next year and a half? Their timeframe strongly implies a next-generation target.
