Is sony Alpha DSLT/DSLR the right platform for learning photography and growth?

Thanks to all of you for your wonderful responses.

While i am convinced on Sony now, I am still deciding the right camera and due to a deal i am getting a77 at just 250 USD more than a57. I am getting tempted about A77 now and wanted to know your thoughts on the same.

i have raised this as a separate thread here http://forums.dpreview.com/forums/thread/3289021 as well.

i will look forward to your opinion.

Thanks

Ash
