The white Makita stuff I've seen has all been made in China. Where are the teal ones made? I don't know if it's true but from what I heard the teal stuff is suppose to be their better line of tools.
Im not sure where the white ones are made but i have noticed the spec's are different form the white to the teal in the impact drivers.
White impact driver 18v - Torque (in.-lbs.) 1,280
Teal impact driver 18v Torque (in.-lbs.) 1,330

The Watt Hours of the batteries differ considerably. On the BDF451, they use 3 AH batteries at 18V, which gives 54 Watt hours (AH * V). The BDF452HW has 1.5 AH batteries at 18V, which gives 27 Watt hours. So the runtime on the BDF451 is going to be twice that of the BDF452HW with the included batteries. What's being done here is that Makita, in trying to get to that $200ish pricepoint, has made smaller batteries for a "Value" line.
The charger included with the white model is a 15 minute charger includes a fan, although it wasn't listed anywhere in the specs for the charger. The blue model includes the 45 minute optimum controller with temperature control via a fan to circulate air through the battery itself. This helps create a more even charge by having the cells in a more consistent state during charging.
Update: Makita will apparently be moving all of their tools to this charger, which will be 22 minutes on a 3AH battery and 15 on the 1.5AH.
Also noted is that the BDF451HW uses a 2 speed transmission and the BDF452 uses a 3 speed. The difference in gearing makes for a 450 vs 560 rating for torque as well. Not that most people will notice the difference in torque, but that shows which markets each one is intended for.
The white model is intended for use in the high-end homeowner market, the DIY guys and low-end contractor market. The blue model is the flagship, with all the bells and whistles, designed for the professional that is using the cordless tools on a regular basis. They're both Makita quality, but they're just expanding their horizons a bit. The side handle, belt hook, and a few other minor differences make the BDF452 the choice for contractors, and most DIY and homeowner types won't even notice those are missing.
Kudos to Makita for being first to come out with a full featured Li-Ion for ni-cad priceing.
