been reading alot of review and seems like pogo stylus is one of the better ones. part of issues usually found are how smooth is the tracking (e.g. if it is rubber tip then it may not drag as well) and how sensitive is it (i.e. read review of how sometimes u need to press hard on screen then can input, esp with screen protector, or even at certain angle dun work). gf wants one as she has nails.
locally, istore sells it but abit ex.. still cheaper than listing i see on ebay singapore though. i think i will be sourcing from HK.
