Comparing the NXT Educational with the NXT retail packs
It is clear that there will be differences in the kits Lego are supplying for the new NXT controller. But what will they be?
Most people who have been closely following the NXT’s development are fairly aware that there will be things like an external DC power supply, cables to adapt existing RCX sensors and possibly enhanced software to expect with the education version of the kit, although the retail one will be available sooner, and unless you are able to approach a Lego DACTA supplier, you may be stuck with the retail version anyway.
Filip’s blog has covered some of these differences in some detail, and is definitely worth a read. He also goes further, and compares the FLL version of the NXT kit.
