Hello people of macrumors i have been using my really old black macbook from 2007
i really love it but since its ageing and cant upgrade ram
so i need to get soon a new laptop in my case new macbook 
I mainly use my laptop for causal web browsing and developing apps in C, objective C, PHP/CSS, Java, and C#...
So i need a opinion from fellow devs about thiese macbooks:
- Macbook air 13 inch with i5 Haswell CPU, 8GB of ram and 128GB of SSD
I do really love the mobility of Macbook air and now that its upgraded to haswell and have amazing battery life and new AC wifi so i wonder if this little fella is ok enough to be a Dev machine or not
- rMBP 15 inch with 16GB of ram and 256GB of SSD
What i really love about this macbook is IPS screen and of course retina display that i could scale to any resolution which is important for web design and the 15 inch screen is better than 13 inch tho currently only downside of rMBP is that battery life is not impressive as macbook air and that current gen rMBP is not updated to haswell and that it doesnt have ac
as i want to change my old black macbook in till August/September
but not sure if rMBP 15 haswell is worth the wait or to go straight away with macbook air or current gen rMBP 15...
