Yeah, i saw i many sites that message for thats "supported browsers" users.
I think many sites are comming very heavy, you know, like Facebook, Hi5, and many others where you with any Peeezzeee and Windowzzz many times you encountered a few problems, anyway i dont fell this resources request in this heavy sites make a big improve, the only thing is its more spending computer resources.
Anyway, my all time question for the Software developers is, its so hard develop a Web Browser?.. You know, becouse i see during all this past year for Amiga was very hard find any Web Browser equal to others OS Browsers, all the time in the Amiga browsers are under the others Browsers, always wanting something, making incompatible with some Sites.
Now, if your Amiga is with OS 3.X, i am aware thats Amiga are making too much browsing the Web in this times (2010), but are nice use that system today!.. but maybe its time to upgrade to OS 4.x. if you want access to sites like Youtube and others. Other thing is the Amiga Configuration, becouse if you have any 030, 040, 060, and 18MB Ram, i dont know how works any Site like youtube in any Amiga with that configuration.
Maybe i will need obtain a Kickstart Chip 3.1!.. and update to 4.X. But the other problem is somethings like the Netsurf Browser, this will not run without Gpx card!.. then in your "very"Classic Amiga (Native Video Mode), you cant run a new browsers..
For the moment there is more to use what's available and see how far reaches
