I own both the 1010 and the 1400, I like both of them, a lot. The 1400 is a more refined tool than the 1010, first it has more power, the ratcheting spindle lock, better dust collection, able to use 1/2" bits and the chip catcher comes on and off without tools. The only down side to the 1400 is the cost, when compared to the 1010, you have to buy an edge guide and the guide rail adapter for the 1400, the 1010 comes with those items. The 1010 biggest asset is its size, small and lite weight, very handy. It only takes 1/4" or 8mm bits and you need a screwdriver to attach the chip catcher.
For me, I use the 1400 a little more, not for the power or the ratcheting spindle lock but for the toolless attachment of the chip catcher and the slightly better dust collection. However, the 1010 gets plenty of work. If the 1010 had the toolless chip catcher, that would be one fine tool.
This is my take, buy the 1010 if you need a small router and/or you don't want to spend the extra money on the edge guide and the guide rail adapter for the 1400. Just remember, 1/4" or 8mm bits only. The 1400, buy it if you want a router with a little more power, 1/2" collet and better dust collection, you'll have to put out the bucks for the edge guide, the guide rail adapter and the 36mm hose to really take advantage of the dust collection. Or, do what I did, buy both!
