sorry twinkie, there were a couple of things about walkers on the link, namely:
Rospa do not recommend the use of babywalkers, for reasons that research suggests that half of all infants who use babywalkers receive some kind of injury.
New styled walkers have been particularly cited as causing significant developmental delay, at time of use, compared with those infants who have never used one.
Baby walker injuries are 12 times more likely to involve stairs.
90% of all babywalker related injuries affect the head or face.
Babies can travel up to seven miles a hour in a babywalker.
There is clear advice to avoid the use of babywalkers to minimise the risk of your child having an accident, it does not enourage walking, infact there is evidence building to show that it can infact hinder development.
