Only 1 usb port is a bit of a strange one. Once you've plugged in a wireless adaptor thats it. The only way this is practical is if using a powered USB hub with the Pi powered from it. Think the B+ with 4 USB's and ethernet offers better value IMHO.
I had to use a powered hub with the model B to reliably use several devices at once anyway. I wonder if they'll end up moving to a better CPU eventually, like introducing a model C or something.
I wouldn't say it's strange at all, because you even said it your self - there's a the B+ if the extra ports are needed.
I think the A+ is great, there are a number of applications I can think off of the top of my head that wouldn't even need USB ports at all, made better by the fact the A+ is smaller, lighter, consumes less power and has useable stand off holes!
EDIT: And it's much cheaper compared to other models, less to worry about if it gets lost on the way to the upper atmosphere or forgetting which tree it had been strapped to.

I think a "Pi 64" would fit well with the 1980's naming scheme, and a 64 bit upgrade would be what it takes to get me interested in one of these. They were always underpowered, had they been another tenner and more powerful I would have bought one.
Though I think what I really want is an ITX format board with a DRAM dimm socket or two so it is upgradable.
The Broadcom SoC that every Pi model is centred around only has one USB port and no LAN connection, for additional ports, models B and B+ feature a 3 and 5 port USB hub respectively, plus a USB to LAN controller.
All that added together, the additional USB ports, USB hub, Ethernet connector and USB-LAN controller, significantly adds to the cost, size and power consumption. Hence, for the applications that don't require that capability there's no need to waste money or power on the additional components.
This looks more than ever like an embedded computer that can be used as its own programming platform. It is now small and light enough to be used in model aircraft or boats, perhaps using a Bluetooth dongle as a radio control from a mobile phone, and this is a place where the lower power consumption would be highly welcome.
I wonder if servos can be driven directly off of the GPIO?
