I'm actually considering a DSLR myself. I'm not hugely into photography, but due to my job I'll probably be travelling quite a lot in the next few years and would love to take pictures.
I love photos taken with a nice depth of field or Bokeh effect and have tried these many times with my point-and-shoot but quality is nowhere near comparable to DSLRs I've seen due to the smaller sensor size.
Would a DSLR help much in this regard? (nice DOF and Bokeh etc.)
absolutely definitely. 100 percent. If you just want to take snapshot and it'll be a fairly minor hobby, you could start with a base model, a 1000d or something.
Nice and small and light. Would fit you purposes well.For nice bokah you need a lens that is nice and bright, or has a large focal length.
The kit lens is fine for snapshots, and you'll be able to get nice dof. I will say again though about the 50mm1.8 . It's a prime lens so no 'zooming' but it's fast, gives nice bokeh, is sharp , very small and light and is great for portraits on a crop camera.
