Most of the web (if you mean that by the internet) is actually orientated for landscape not portrait. One of the raved about features of the original RIM handsets was that the secreen was wide enough to read emails and sms in a more 'natural' format. Most latin based charactersets are designed to be read in horizontal lines. Kanji is another debate altogether I'll grant you. Terminal, try telling any serious user that portrait is preferable for that.
