I've asked this before [1], but I've yet to receive a satisfactory
response: What about the desktop? The killer feature of this new SDK,
we've been told, is that it'll work on the phone and the desktop
equally well. So,
1) Is the desktop moving to a rolling release? As an LTS-to-LTS kinda
guy, I certainly hope not.
2) Will the SDK be kept up to date via backports or PPAs on the
desktop? So far, it hasn't happened.
3) Will the SDK be completely backwards compatible? Obviously not --
the point of versioning it is to add features.
4) Will there be some way for apps to react to the framework they find
themselves running under? So far I've heard "no".
Without any of these, we app authors have to (a) target a framework old
enough to be on the oldest desktop we're interested (likely a LTS, and
do you really want people using Ubuntu.Components 0.1 until 2016?) and
(b) hope that the old frameworks are completely forward-compatible on
newer images (they aren't). Already, I find that the only way to get
my app to run both on a current device and the 14.04 desktop is to do
Loader hacks to detect which framework is supported [2]. It'd be much
better if there were a straight-forward way to do this.
