Me too I had a Series 0. Then the battery inflated and cracked the display open about 3 months ago. Would have been about 200$ to repair, as it's out of warrant

Me too I had a Series 0. Then the battery inflated and cracked the display open about 3 months ago. Would have been about 200$ to repair, as it's out of warranty. Luckily I called Apple Care, explained the situation and got a free replacement unit. To my surprise I got a Series 1. The difference in performance is incredible. I'm now using apps like Bring! for shared grocery lists, OmniFocus and others much more.
