My recent experience is to the contrary: having re-flashed back to standard for a day with no apps, no swappolube, no overclock and no CSSU I found the device uninspiring, laggy and somewhat restricted for all but the simplest of tasks. Strangely enough, I did begin to appreciate the build spec & quality once again.

I soon began craving functionality and features found in basic Symbian S60 devices, nevermind Android or iOS UI goodness.

Restoring all my apps and performance tweeks also restored my conviction that N900 is still one of the most accomplished, powerful and under-exploited devices available.

A day as 'standard' is about all I could take!
