today's my birthday, and I received the S3 version with GPS but without cellular. I used to say I didn't see the need, but it's dope so far. It's very convenient. and I'm shocked that I can actually type on that little ass screen by spelling out the words fairly quickly. there's a shytload of apps on there that synced from my phone and as an avid runner, the built in nike functionality will work well for me.
my wife previously bought me a nike GPS watch, but that shyt broke. and I had a nike fuel band and that broke as well. the nike watch broke quick, but the fuel band broke after like 3 years of regular use.
my wife has had the series 1 thru her job for the last year and she likes it. so I guess she figured I would like it as well since this one is waterproof.
