The AWS App on iOS is pretty much done, at least I have made readonly part of S3 and EC2 works, and I don’t think write operations (create, update, delete, etc) are feasible to mobile phones.
I’m moving to Windows Phone now, trying to build up similar App in term of functionality – I’m not sure if I can build things with similar UI since different app store may have totally different tastes/rules on UI standard, better follow what they asked for.
I wish Windows Phone development will be easier thinking of I’ve done .Net/Visual Studio development before, let’s see – I give myself 2 weeks, and will spend no more than an hour per day.
Actually I tried both Android and Windows Phone the other day, trying to get basic idea of development. Obviously I don’t like Android, either because of I’m not a Java fan, or because of ugly interface of Eclipse – it may only be that ugly on OSX though, but I don’t have space (read: memory) to launch such a fat IDE in my Windows VM so leave it to the last.
