Sony Ericsson P900

I heard a comment that the p900 speaker was a little weak as far as pda's go. any comment on that? also is the 800 and the 900 equiped with the same speaker? Also for reading text is the 800 ok? I understand the 900 has tft 65,000 colors as opposed to the 800 having 4,000 and some. I don't care about colors but my eyes aren't so good so I need to have good clear text. good backlighting etc.
