So... let's see. You guys are attacking a person who - admittedly crudely - has stated some problems that many others have commented upon.

The path to playlist creation is indeed a bit convoluted. Here's a few on this site alone...

Battery life? Here's a few on this site alone...

Memory faults, problems... and not just including rootfs? Here's a few on this site alone...

Now, with a calm mind and whole hell of a less fanboy attack mode, let's be honest. There are some problems. These problems are amplified only if you are lacking: knowledge, the ability to use the search button, haven't done your research before purchasing the N900, or better yet... lack the willingness to learn.

Now. Instead of this swarm of a whole bunch of usernames that have only signed up within the last few months dictating how this forum looks - I hate the majority of the responses in this thread, stopped reading two pages in - then why not try to help and convert a person to see the same stuff as you N900 faithful see?

Sheesh. It's easier to attack than answer, I ****ing get that. But you know, how about a different route.

OP, you state memory full. Do you have which applications you were attempting to use/install when this happened? A full list would help you out fully.

The playlist creation, it is indeed a bit "complicated" but it's functional. Which programs are you used to in the first place? I think that might dictate what you might be expecting.

Battery life... are you running this stock or overclocked? Are you signed in all day and using heavy IM, et al?

If you start to answer those questions - which admittedly you already might have, I stopped reading as of page 3 or so - then let's bring them back up and let's see if there's a solution.
