He mean that many companies - Apple to name one - introduce in their upgrades for older devices (on purpose) things, that decrease performance.

He also asked if anyone know about such practices being done by Nokia to *any* their device, as he would like to know that he should stay away from further Nokia products (as if WONTFIX would not be enough reason ). Said that, he also noted that PR 1.3.1 was update boosting performance (which I disagree totally), and that N900 performance is increasing due to continuous community effort (where I agree totally).

If I was able to parse OP, I think it wasn't so impossible to read it with understanding Especially, that he wasn't using 'luser' style form of writing - just some short forms.
