Err, aren't *you* now disagreeing with facts ? ;-)

It's a *fact* that I found X via SSH with only 400kbps upstream from the far end quite workable as long as there weren't bitmaps involved. For text work it was "like being there" for me as I remember - can't check now as I don't have an ADSL line, and hardly anything actually running X. I'm a vi person though, so that may well make a difference - how "chatty" is emacs ?

It may also be a *fact* that for you it wasn't an acceptable experience. That doesn't mean that (as you put it) you cannot expect a usable experience with ADSL - and that's leaving aside the different ADSL services, such as those with 1Mbps+ upstream. I suspect some ADSL services may have higher latency than others, which may have a bigger impact on perceived performance than bandwidth.

Perhaps better expressed as "you may or may not be happy with performance if ADSL is involved - depending on your task and your perception of performance". Or just YMMV !
But we're going off-topic now.
