About two weeks ago I purchased:
non-retina MBP - 13-inch: 2.9GHz 8GB memory 750GB hard drive

and today I am totally confused if I should return it and get:
1. 13-inch MacBook Air 2.0GHz Intel Dual-Core Core i7, 8GB memory 256GB Flash Storage
or
2. 13-inch MacBook Pro with Retina 2.5GHz 8GB memory 256GB flash storage
or
3. Keep my non-retina MBP

I recognize the $$$ difference and willing to go up to spend on rMBP 256GB 13-inch if that is the best machine to buy. 15-inch is not an option for me.

The use of the machine is lot of web browsing, connecting to PS3 to wireless stream video and some video/movies viewing on the laptop itself in addition to Mac Office for documents.
No advanced video or photo editing or gaming.

Please suggest as I have to leave US in a week for a long international trip and want to change my machine before that.

Thanks in Advance!

Honestly, pretty much any computer can handle what you're doing, you don't need to upgrade unless you want to. Beyond this you can plug pretty much any external hard drive into the PS3 and it will play 99.9% of your video files. For anything not supported I just plug into my TV with an HDMI adapter [which is my setup](but again, even if you're streaming you don't need to upgrade your computer, my Rev 1 MBP from 2006 can do this)
