Thanks for all replies! I have pretty much decided on 13" with 8 GB RAM and 128 GB SSD. 11" is too small. It's lovely but it's just too small. The 12" Macbook is GORGEOUS, tiny, cute, lovely screen and the worst keyboard I have ever tried. I tried to type a sentence and somehow managed to miss half of the keys. The 13" is going to get one of those flush SDXC bays with a 256 GB card inside. I don't mind the non-Retina screen at all, especially when it costs 350 euro to have it and I lose a lot of processing power in return. The Pro is too heavy (and pricey) for what I want to do with it.
Now I hope Apple don't manage to either take it off the market or bump the price before I've got ca$h to buy it
I have a 2013 11.6" MBA that was not may main machine until I went to a remote tour...it's a base 4Gb RAM/128Gb SSD machine so I added a 64Gb Sandisk USB3 flash drive to it since it didn't have a SDHC slot (being an 11.6" machine) and its been fine for daily use coupled with a 24" external monitor.
The portability has been great!
