i was just wondering how long everyone left their n900 before re-flashing? I've had mine just over a year now and have only updated the O.S. and never reflashed the eMMC image. Also i've ventured into extras-devel which not knowing much about the workings and only being a user i may of messed up my device, even though it seems to be working well.

With my laptop/pc i try @ least once a year to do a complete install of the O.S. specially when i've been "messin around" with it.
As i said it seems to be working fine but as with anything you use on a daily basis you get to thinking this doesn't seem as quick as yesterday/ CPU seems to running higher than before/ hanging and lagging.
Are there certain tests you can do to show you all is not well and it's a start from scratch time.

Cheers
