Ordered mine yesterday, sport white, 38mm... Come on June..
When the second gen comes around, if the apps and tech are there, I will definitely get the steel version but for now the entry level is best when the technology is new. I will need to get some different bands at some point though to change it up.
Reasons for me to buy it, I run. I have a bluetooth headset. The run apps I like, particularly Zombies run which integrates a story with my music, are coming to the watch. To have music on my wrist and not have to carry my phone ( you can add up to 2 gigs of music directly to the watch via playlist with out needing to carry the phone, add to that fitness tracking, bye-bye fitbit, and I have less to carry with more functionality.
On a personal note, I have been a type 1 diabetic since I was 12. I wear a monitor that tells me my sugar every 5 min. This is an additional piece of equipment to carry. Dexcom (the Co that produces the monitor) made an app for the watch that will take away the need to have the monitor on me to know where my sugar is. 1 less thing to carry. Now on a run all I need in my pocket are my key and some glucose for emergencies, no phone, no meter, yay!
Ultimately for me this is a must have:
A time piece, an iPod, a Fitness tracker, Heart rate monitor for running and fat burning, and for me specifically its also a medical device.
What more could I ask for? I am so excited and already looking forward to the next gen!!
