Catorize and ApMeFo both expose a bug in hildon causing drain. Python widgets cause a leak that causes heavy swapping in about 48 hours. This is also manifested as high CPU usage when unlocking phone. User tests in bugzilla suggest it also happens with no widgets, only slower. I reboot every 48 hours. It's not unusable, but noticeably slower than after reboot and has noticeable delays due to swapping. IIRC, not even 1.3 will fix this.
They're maemo and MeeGo... "Meamo!" sounds like what Zorro would say to catherine zeta jones... after she slaps him for looking at her dirtily...
