well it will depend on ur internet needs.
i personaly use dsl.
cable would offer more but rumors have sadi that dsl is more reliable.
i havent tried the alternative so i would know but i enjoy what i have and i'm considering upgrading it from its curretn 384kb status to 1mb.
Thanks for the advice , seems to consistently favor DSL...
Have read cable has higher bandwidth but is more dependent on how heavily your neighbours are using it. That's be a hard one to figure out beforehand though.
If anyone else is interested, http://www.dslreports.com is a useful site (although has very little information on UAE).
