I use it every day
I've used it solidly for over a month now and it has definitely helped me increase my walking - giving me that added push to get out the door and make an effort. It is also fun comparing your activity with a partner, or in my case a daughter.

Walking fun !
Nowadays i really like to bring the Activity Meter with me when i'm going out, it record every step i walked, i can also check my family whether or not they are lazy, who has the Activity Meter.

Very good
I realy enjoyed it at first. But after a while I didn't have much to with it. But then I ordered the Weight Loss Coach and started using it again. It is really cute, but you need to have goals, otherwise you'll give up on it.

well... Personal Trainer: Walking VS My Health Coach (with pedometer)
My Health Coach gives more advices, it tracks your meals and stuff

Personal Trainer: Walking... givs less advices. It doesn't follow the WEIGHT LOSS target. It tries to put your life/day cycle to the better one.

I own both... Personal Trainer: Walking is just a game for fun. Don't ecpect much

cute
Not much of a game, but Personal Trainer: Walking will definitely keep your feet moving. It's a fun accountabili-buddy. Neat to see the breakdown of when you're active, and the online stuff, though a little weak, has its charms. I hadn't turned on my DS in probably 2 months before picking this game up, and turning it on to check my daily rythm reminded me to play a game also :) I was hoping for a Nike+ killer, and while Personal Trainer: Walking isn't that, it does get more use than my Nike+ simply because the hardware works quite reliably.
