I'm looking for some advice/input about the major differences between the Series 2 and Series 3 watch. I currently own a Series 0 SS and am ready for an upgrade. I have been looking at both the Series 2 and 3 watch and am wondering the biggest differences. I want to stay with the SS line for the sapphire glass. I hav owned my Series 0 since launch day and have NO scratches and have never had a screen protector on it. LOVE that! Anyway...I could purchase a Series 2 used (Swappa) for around $300-350. The Series 3 is $600 (open box Best Buy). I like the idea of a cellular option, but am almost SURE I won't need it except for on a rare occasion. I also like the idea of the newest watch since I'll probably keep this one for three years as well. I suppose the Qi charging standard is a bonus...is the 3 brighter than the 2? Does anyone have a Series 3 that they just don't use the cellular on? I assume the watch will act as normal if I don't connect it to my carrier. I'd get the GPS version...but that's not available in SS. As you can tell, I'm leaning toward the Series 3 for many reasons...but also consider the Series 2 as a great upgrade from Series 0. I'd appreciate any input from those that have experience with the 2 or 3. Thanks for the help!
