I got one the other day for my dad via Tesco Direct. I use a Nexus 4 myself. I've been testing it for a few days.
The moto is very good, really nice bright screen. I benchmarked my phone with it and the moto got a better score than my Nexus 4!
Good: screen, speed, weight, should get decent upgrade support as it's a Google company, some nice accessibility functions (good for my 75 year old dad), not much Motorola specific software pre loaded
Bad: Camera isn't very good indoors, on button a little rattly which can be annoying if you have 'vibrate on key press' activated, doesn't come with mains charger
For £99 it's a total bargain, punching well above it's weight.
