I have been surfing Ql since 2yrs now and have never faced any of the problems that you mentioned, I even check it on my cell phone through wi-fi at coffee shops etc and dont find viewing pages to be a problem coz of there length.

Maybe u need to upgrade your browser to the latest version.. im not too sure

I have used dial up to chk QL and it works fine..

Though I have a good 1mb Adsl line at home :)
