Android developer events are open to anybody that is, or is interested in, developing for Android. I went along to learn. They didn't advertise that you'd get a free phone (wisely), so that was a nice bonus. I was careful to state that I only just got the device and that my normal handset is an iPhone.
1. Apps from the Market install automatically and in their entirety to the internal memory. If they wish they can of their own volition download additional data and write it to the SD. It is simply not true that "all the other files go on the SD card" — files that you specifically write code to place on the SD card go on the SD card, and your membership of the Marketplace does not automatically get you a secure place from which to download them or a way in which to sell them.
2. in summary, if I should launch the built-in IM client then I have no way to quit it. I don't care about the technical stuff underneath. Regardless of the technicalities, "that's how it's supposed to work" isn't a particularly convincing defence against an allegation that something was misdesigned.
An example of Android's overly technical approach to an appliance audience:
On the iPhone there is one place that lists installed apps, which is the same place on which you rearrange apps and the same place from which you uninstall apps. It's all one screen. As a casual user, I therefore understand that the icons there ARE the apps.
On the Android, the top screen is a Windows-style desktop. You can add shortcuts to apps you like there, rearrange them however you want and remove the shortcuts, but they in themselves are not the apps. They're an abstraction that requires me to abandon spatial thinking. All apps are listed in a separate screen through a BlackBerry/Symbian-style horizontal scroller, where they appear in a fixed alphabetical order. So I can think of the apps in there as the actual apps, but I'm not able to arrange them how I want. To uninstall apps I have to drill down through settings, applications, installed applications, tap the one I want to uninstall, tap to uninstall on the next screen and then tap to confirm that.
I don't think you can claim that isn't more technical. There's no consistent metaphor and I'm required to deal with the OS rather than directly with the apps to uninstall.
I guess you're not design minded if you can state that "to claim the fonts look cheap is just stupid". Helvetica is a design classic to the extent that there is even a well-received documentary film to celebrate its 50th anniversary (see http://www.imdb.com/title/tt0847817/). It also costs money to license, which is no doubt why Google haven't been able to include it with an open source software stack. In fact, it's why Microsoft don't include it with Windows — they use Arial which is almost indistinguishable from Helvetica at normal screen resolutions and not desperately different on paper.
I don't know what Google use in Android, but it's a long way off both. Go on rallying against the typeface world if it fits the team you want to support, but don't try to claim it's everyone else that's being a fanboy.
An additional complaint that has struck me since the event: the glass or plastic cover they have on the Nexus One is clearly quite cheap and prone to scratching. They even supply a little pocket bag like the iPod socks that Apple used to sell separately to protect the old similarly-scratch attracting iPods. Conversely, the iPhone and the iPod Touch have a huge slab of heft optic-quality glass on the front. I'm sure it adds weight, but I know which I expect to last longer.
