D.Lovelee- The traffic is indeed terrible during the rush hours, which run quite long during the day. I try to combat this by being asleep all day and out all night
Motobikes- not sure what's wrong with them. I have one and enjoy it immensely. I buy four liters of gas and it lasts me a week or two of riding around the city. Granted often I'll drive someone else's newer bike around town.
Air pollution - yes it's bad. Air is much fresher at night though.
Touts- I had to look it up but yes, touts are annoying. A tout is any person who solicits business or employment in a persistent and annoying manner. They are here, especially in D1. It gets tiresome.
Backpackers- I like meeting backpackers from Ireland or England or South Africa, etc. Also, they are here on vacation and have no job so any night you want to party just go to the backpacker district and it will be going on like a weekend.
Clean Water- Yes you cannot drink water from the tap. This is standard in SE Asia, in addition to many other parts of the world. It's easy to buy cheap bottled water and it's important to remember to only drink bottled or filtered water.
Most places in HCM suffer power outages twice a month for an hour or two each time I was told when I got to the city. It's been my experience so far. But it's not been too disruptive for me personally.
I've had from very slow internet to very fast internet in the city. Find the right internet provider and you will have very fast internet.
Clean food - I've gotten sick eating seafood twice in my 3 months spent in Vietnam (though never in HCM). Still I continue to eat seafood because it's so damn delicious here.
I'm not trying to contradict your points, but just to add my input to your valid opinions.
