I saw a baby being front carried. Yeeks. Like hanging by the crotch. Now I totally understand what this means. I think it's ok for short trips but not so for longer carries.

Personally I don't like a real traditional mei tai. The MT is self-tying so it's very troublesome, and you need to tie it really tightly in order for the MT to work properly. If you must get a MT, then get a Buckled one. Think Dumbo has it.

I would say that each has their pros and cons. There's no better one, just a matter of preference. Even for me, sometimes, I like the Beco (no hanging straps, useful hood, etc) and sometimes I like the Connecta (no interior cloth so takes little time to carry baby in and out and don't have to remove the carrier to breastfeed).
Carriers
I think I am happy with my carriers lot. However, my biggest complaint will be shoulder pain from carrying my handbag!!! Heee. All the burden on my right shoulder. Baby + handbag = jelat! I also don't know why my handbag is so heavy. Even the husband thinks my handbag is heavy. Sigh, but on top of what I usually carry, I only have one more jujube bag for her diapers.
