I have used and tried the following:
1. Opera Mini v3.1.7203 advanced
2. Opera Mobile v8.6
4. Netfront v3.5
I dislike Opera Mini because you have to go into Java, and it's not that great for me. Yes, it is fast but useless for my needs.
PIE is usable but not great.
Opera 8.6 is very good, handles downloads well and I like the tabs. This is my second choice for a ppc browser.
Minimo is crapola...it is actually unusable it is so slow. I use Firefox on my laptop and it's great, but minimo sux like electrolux.
NETFRONT is the way to go for mobiles!!! You get VGA resolution up to 1024x860 I think and it has smart scroll which is as smooth as silk. It is also much faster than any of the other browsers above. I have only started using this and I haven't tried downloading anything yet. It also has tabs and lots of user-defined settings for display etc. Very fast and the closest to a pc browsing experience IMHO.
I will keep you posted as to my experience with Netfront v3.5.
