There is a NEW version of the Iris Browser and it is pretty good.  I have been using it on my Palm 750 and find the experience to be pretty stable.  It still needs more work but I think you will enjoy it.

Iris Browser Beta 2, which is now available for free download, has been tested on a variety of Windows Mobile 5.0 and 6 devices, including Classic and Professional editions. A 400 MHz CPU with at least 128 MB of RAM is recommended at this time, though it is known to work well on 200 MHz processors and 64 MB devices.
