The challenge with "faster install" is that we want to retain flexibility. The basic mode (aka Partner mode) goes in VERY quickly - you can virtually let it go with default programming. But it doesn't do much. One solution that we use is to configure via Excel spreadsheet then import. This makes copy/paste very quick and easy.
SD card troubles have mostly gone away. Bugs and patches are on every system I've installed in the past 20 + years. The more complex, the more possibility for a bug. 1A2 had very few bugs... It is true that other manufacturers seem to have fewer issues - but it also seems that those systems have less flexibility and fewer features. So, like many things in life, it is a trade-off.
