In order (as far as I remember them):
Nokia 3410
Motorola RAZR (the original one)
Motorola RAZR v2
LG KM900 Arena (the first """real""" smartphone I owned)
Motorola Atrix
Motorola RAZR HD
Motorola X Style
Motorola G100
Bought all of them on my own dime, though only the Nokia, LG, X Style, and G100 were new, rest I got used from others so I was usually at least one or two generations behind.
I can highly recommend the G100 as workhorse. That thing is extremely strong while only being about half the price of a flagship offering, huge battery, and no uselessly bloated android. Only downsides are the lack of front facing dual speakers, only 20w charging for the 5,000mAh battery, and that the security patches lag behind by a month or two. But beyond that you get serviceable cameras, can hook it up to your TV as emulation box, and the Snapdragon 870 makes everything butter smooth.
