Unfortunately I have to disagree with Menneyysys about Opera... 8.65 is/has:
- buggy
- a memory hog
- messes up most pages' layout by completely missing font sizes on my Universal
- fails to constrain the page width into the screen width, unlike NF that does that correctly on every page I tried
- HTML, CSS, JS engines sub-par with respect to NF (look at
www.gucci.com in NF and opera... sure, NF stops at the splash screen, doing the fade effect, but that's better than the pale white display of opera!! like on most of those complicated JS websites)
- bad usability: shitty joypad navigation that makes the page scrolling crazy left & right when you're only pressing the down button, because opera has this bad habit of focusing on the hyperlinks AT ALL COSTS, and it catapults the cursor on the other side of the page without you even knowing WTF has happened
- zero customization... you can't even disable the cache or set the size limit, coz it won't work! it grows over whatever limit you set! good job, Opera, you mess up things as easy as 1+1! (and yes, i'm using the latest version)
- for the "sake of memory optimization", I imagine, it unloads & reloads the images when you scroll over them, and it's a bad visual artifact... and still it's more a memory hog than netfront
- has no way to save bandwitdh or rendering speed, like a rapid render mode, that NF does
- has no enhancements like page miniature previews, thumbnail'd bookmarks
On top of that, I have to say that teh guys at Opera seem to ignore their Windows Mobile products... releases come out slowly... there was an endless beta period, whereas OM8.65 for symbian was released in a snap.
The only and one bright side of opera is that it better supports the WMP plugin.
