The N900 browser has quite simple solution. Trying to run modern browser will never work - the device does not have enough RAM and fast CPU for it.

But the solution is quite simple - use fast server to render pages for you. Did this myself with VNC. I had chrome running on my debian server. It was very usable compared to the native N900 browsers.

We could have app for this. The basics could be really simple. Send url to server -> receive rendered png.

I always wanted to write it. But i am not coding in my free time and not using N900 anymore, alhought i miss it - it was greatest phone of all times, i love it (both software and HW).
