I have mine set to the max (64 MB) and routinely use all of it. It would be nice if I could easily set it to a user defined size (without having to resort to the command line). This is about par for the course. A lot of Nokia's settings are similarly limited to just a few choices. For example, in the "Display Settings" I can't set the "Switch off display" setting to anything longer than 5 minutes and "Brightness period" to longer than 2 minutes. I should be able to specify a user defined period for both, up to and including disabling that power management feature entirely. Not being able to disable this and other power management features has limited my ability to use the 770 for certain roles on more than a few occasions. Ensuring that the basic platform is adaptable to the 1001 uses that Nokia didn't think up is going to be a big part of the success or failure of the Maemo platform.
