I have a Bosch MX25, to get me to change it would require more than a color change. Although I would like the tool-less blade change the Bosch feels much better in the hand and that's more important to me.
Bosch has a tool-less blade change in Europe and I expect we will see that here in the new year. Right now I also have the Bosch PS50 multi-X (12V) which I sometimes use with a "second" blade to avoid constantly changing.
If Dewalt does a make-over on the multi-tool (like their 12V/20V Max tools) the decision to add a yellow & black multi-tool would be a whole lot easier for me.
i would buy it in yellow.
