Yeah, Google's official market is the glitchiest thing I've seen in a while. I will note that I've had no problems with the concurrent downloads/installs failing since I bought a Galaxy S II (my previous Nexus One had that problem constantly), but aside from that, I have every problem you described and several more. I have a Xoom as well as the SGS2, and I'd estimate that 70% of the time, the two devices disagree on what apps I've bought. If I buy one on the phone, it never shows up on the Xoom, and vice versa. The web interface is the only one that has a consistent picture of apps I've bought. However, it doesn't always work. On several occasions, I've gotten into situations where an app has an update available, but trying to update just fails silently (and immediately - you see the download indicator flash for maybe a tenth of a second and then it just vanishes). The only way to get past it is to use the web interface to send to a device, which will also fail, and then retry the update from the device. This doesn't always work, but if I repeat it enough times, eventually it will. Usually at least. I have had to, on a couple of occasions, resort to googling for an apk file that I can put in my dropbox account to manually install from the phone -- for apps I got from the Market already. I think I've only had to resort to a web search once. Usually, I can find the apk/odex files on the one device it install on and pull them from there. Isn't it great that I'm considering "adb pull" as a victory for installing an app that has a big "Install" button right next to it? Some apps show up one day as available in my country (Iceland), and then 15 minutes later they aren't. Sometimes I get notified that updates are available for built-in apps like Maps. Those often fail, and there's no way to get rid of the update notification. In short the Market is a train wreck, and that's not even considering the poor state of discoverability and management. Amazon on the other hand has at least solved the problem of producing software that functions to a minimum standard of fitness of purpose. Their organization doesn't seem much (if any) better than Google's, but at least I know what's going to happen when I click a button on their site. I'm confident that I'm not going to spend the next 20 minutes hunting for an apk file for the app I just bought because the store I bought it from went up in a puff of smoke for no apparent reason. The sad part is that even with all this, I still prefer Android, and I've been a heavy user of both the iPhone and iPad. Just imagine how much nicer it would be if they gave a shit.
