Reply to Macbook Air 2009 - Good for Djing?

My friend offered me his macbook air 2009 after my laptop got stolen for only 350$...

I'm wondering if :

Processor and memory
1.86GHz or 2.13GHz Intel Core 2 Duo processor with 6MB on-chip shared L2 cache running 1:1 with processor speed
1066MHz frontside bus
2GB of 1066MHz DDR3 SDRAM onboard

Can run traktor / Ableton without lagging?

I also know about 1 USB port and No CD, but hell it's really cheap for 350$ and it's in good condition..believe i should go for it? Or in the long run it'll be a waste?
