I just received my shipment from brando, in which I got a Pentopia stylus for my 860.
the stylus is a wonderful improvement over the piece of * that came with the 860. the telescopic feature is nice - it's not sprung like the Palm T3's, but it auto-extends as you pull the stylus out of the Z...
* the tip is compliant and feels just right
* weight and balance is excellent
* length when extended is a vast improvement for middle to large-sized hands
I'm not sure how long the ball pen would last, so I'll keep it's use to a minimum as I don't think there's a big ink reservoir for it.
