This way you get the most support for Windows Mobile (the old one, not 
the Windows 10 one) devices as most run on v4 processors. That doesn't 
mean though that Windows CE doesn't support newer devices. And if you 
target only newer devices you may set the subarchitecture higher. For 
example the HTC HD2 (one of the last Windows Mobile phones and *the* 
Windows Mobile phone, since it's even capable of running Windows RT ;) ) 
has a ARMv7 CPU.
