my current setup to get a decent browser:
vpn vnc to a 2 ghz x86 server
you get up to date browser versions + extensions
you pay via increased 3g traffic and slow downs on video heavy websites.
you escape the shortage on good arm browser and the shortage of cpu power and shortage of available memory of the n900.
The browsers arent fingerfriendly by default/at all.
pro and con you have the fun of setting it up
