D3100 for sure. Latest model.

Even if 1100D is in the market, I personally think D3100 still better than 1100D. Google up and compare the spec for yourself, you may see a better and clearer picture 

w/o AF you have to do focusing manually.
image you twisting your lens until you have the proper focus of your subject.
very hard to explain since you don't have the lens yet.
but as for me manual focus is very hard especially for moving object.

in short, Autofocus helps u get accurate(most of d time) focused image in convenient n fast way
imagine if those compact cameras dont have autofocus, there'll be less ppl doing camwhore 

that is wat u call auto focus (AF)

if you are opting for nikon entry level DSLR, you wont be able to use AF if the lens does not have this function where else for canon, you can do so bcos canon has a AF motor built-in inside the camera...

Wrong, it is because all Canon lens have motor built in. Nikon on the other hand some lens such as the cheap yet good 50mm f/1.8D does not have a built in motor but has to depend on the screw drive from the body.

The cheapest should be the 1855 kit lens

35mm f/2D up for grab

The cheapest should be the 1855 kit lens

you're asking if Nikon is better than Canon in a Nikon thread ???   

Both also good, it depends on individual; Some prefer Nikon, some prefer Canon, some have BOTH. Don't choose what others like, choose what you feel is best for you.....

And do you really need a DSLR? What are you looking for? Are you just buying it's cool to hold a DSLR? If you want easy to take good pictures, and you don't plan to invest in photograhy, Point and Shoot camera might be a better choice and value for money.

Have you tried using one DSLR? For Nikon, you can try out the models in Nikon Centre @ Berjaya Times Square. The lens is kit lens, try it and see if like it. Some people (not mean you), they might not really know what they want and think DSLR is what they need, but after getting one, they find it harder to handle, heavy, bulky, and the kit lens can't offer the quality they want, but they're not willing to invest on better lens which is what they want for the quality.

Anyway, if you're looking for DSLR, then try it out yourself to know which you prefer more. Both Nikon and Canon design is different, the menu system is different, etc. No point buy Brand A because people say it's good, then later you hold/touch/feel/use Brand B and you prefer Brand B.
The camera is just a tool for photographer, choose what's best for yourself, not others.

the D3100 doesnt have a built in motor for focusing but most of the modern Nikon AF-S lenses have built in focus mechanism in them ...

all new lenses of nikon come with AF. Worry no more !

It is a kit lens, if you buy D3100 it comes with one.

all the AF-S G lens come with AF build in motor.

eg:

35mm f1.8G  which have the motor while 50mm f1.8D which doesnt have build in AF motor ,

This is why i always recommend canon for newbies, less worry about lens can or cannot autofocus

If enthusiast level then only recommend nikon

oh ya , that on of the important aspect too .
