Dillo (and jwm and the other applications) were chosen for their low memory usage. At the moment, on a bare wii linux system, there is only 3 megabyte free ram available, the rest is swap space. So i dont think chrome/chromium will run very well. I did check to see if there actually is a chromium package available, but unfortunately it gives an error: QuoteE: Package 'chromium-browserby flits - Wii Linux
I also had a problem getting wireless lan to work: while running system-->configure wifi there is a fast black errorscreen after it asks to bring up the wifi and then it says "you have completed the configuration, but it doesn't appear to completely work". After looking into it more closely, the actual error during the fast black screen is "SET failed on device wlan0 ; No such device"by flits - Wii Linux
