Bests & Worsts Reviews from Amazon

I'm on my third K3. I had a K1, never got around to getting a K2, and was delighted to order a K3. The form factor is excellent - small, light, the contrast is gorgeous, they finally have reasonable storage. However, the first one crashed and froze and crashed and froze until it turned itslf off, although fully charged, and won't turn on again. Replacement #1 has strobe effect - it sort of stalls out and blinks rapidly. Replacement #2 freezes and restarts every time I try to turn the page. On each restart it has a different number of items listed. Sometimes it restarts just sitting there. So 3 out of 3 have been bad. This is the first day I've had #3, and the battery has gone from fully charged to 30% in 5 hours, wireless off. Amazon now says it's a software issue, which absolutely makes sense, but it's hard for me to understand how issues of this kind got missed on testing. This isn't (or shouldn't be) new to Amazon. I expected issues like this with the K1, because that really was early adoption, but that thing just soldiers on, short battery life, dinky memory and all - at least it *works*. So now, per support, all I can do wait and see if the update they're pushing in the next week will resolve all this stuff, and dread whatever new problems the update will bring. At this point, the bloom is very definitely off the rose, and I'm not throwing away the box the latest K3 arrived in, because right now, I don't believe Amazon can make this right. I very much regret how much of my content is tied to Amazon's proprietary format, and the only reason I'm waiting this out is because I've got 2 years of purchases in the Amazon format that I don't want to walk away from, but I'm getting there. The longer this goes on, the closer I am to throwing in the towel with Amazon. It's a lovely little device to hold and look at, but none of the ones Amazon has sent me work, so be very sure that you're willing to invest hours in calls and emails to support with no substantive result before you buy. The folks at Kindle Support are being sweet, but honestly? I got the first K3 less than a week ago.
