If you can afford it, get it. You can certainly learn good braking skills and defensive riding techniques with or without ABS and arguments that you will come to rely on ABS rather than riding skill are basically telling you that you're too stupid to learn.
There are other threads on this site that comment on ABS/non-ABS. In those threads, I think you will find, as I did, that most of the riders with ABS have rarely, if ever, had to use it. The ones that have, however, seem to feel that the ABS kept them upright.
Good riding skill without ABS is better (perhaps) than poor riding skill with ABS, but good skill with ABS is best.
I agree with Wynne's assessment that real world braking distances will be no greater with ABS than without it, but ABS is more likely to keep you upright in the process.
