Orbit & texting, or another phone

Im looking at getting the Orbit. Generally I like thereviews everyone has
for it. My only concern is that I send about 1000 texts per month, will i be
ok on the orbit or will get get pissed off with it, and go back to my
current SE W800i. I tend not to call people much, but text a fair bit, so
texting being ok as a big concer. Also while I think about it, it will be in
my pocket all the time, so is it likely to get damaged easily? If so I'll
probably go for the SE K800.

Any thoughts,

At a loss,

Dave
