Re: Wasps
I actually use a Nexus 5 and whatever PC is best suited to my needs - my use of CAD dictates Windows over Linux or OSX.
CAD has exposed me to some UI conventions that I still can't believe aren't more widely adopted such as Pie Menus. I have an interest in 'pervasive computing' only because I've uses for a 3D scanner.
I'm sanguine about swappable batteries, learnt the hard way that SD cards on phones are a sub optimal experience. I'm dubious that a completely modular phone is useful, but feel that a bottom edge-mounted USB port is not ideal for expanding a phones capabilities for a whole range of niche devices.
