All in all, the sites I visit normally work well on it. Much better than they did on my iPaq (even with Opera Mobile). Speed is not bad except on really heavy javascript laden sites. Flash video's hit or miss - if it's fully cached, it'll usually play without hiccups. If not, it might drop frames (so the video's a little stumbly).
Pretty much any site that doesn't use plugins should work if it works in Firefox. It's the same basic rendering engine.
All of my banking sites open up just fine, too.
I'm happy.
My only complaint is that I can't use my traditional desktop style of browsing - loading up a bunch of tabs and then going through them one by one. There's no hard limit, just if you open too much it'll start showing signs of being taxed.
In general for me all these news sites and major network sites that use flash and all sorts of different new technologies really kills the web experience on the N810.
Pages with a lot of images, videos, flash, tables, dodads, gizmos and gadgets all render slowly and are troublesome to navigate but most work still do 'work'.
Pages that are really wide seem to produce the jittery screen dragging problem ive reported before. Actually every page has been doing it for me but larger pages are worse. Hold down and drag the page , then stop but stay holding down and the page will go all jittery as if its confused on to which direction to scroll to, wider pages will really tweak out no mater the content on them. Yes I did the screen calibration.
I have a Kubuntu install on an old 500mhz dell with 128 megs of ram and it processes web content (using Konqueror) a lot faster than the Nokia with Maemo. Theres no comparison it's like night and day difference.
Have anyone done a direct rendering speed comparison between the mozilla bowser in os2008 and opera in os2007? how smooth is the scrolling on the new browser? I am asking because i find the microb browser in os2007 to be slower and not very responsive to scrolling. i wonder if the new bowser is any better or just as bad.
i found my 770 2006 doesnt work to well with msnbc.com any more. loads to slow and often hangs up. i think they changed the web format, i wonder if someone with the 810 give it a try.
