Hi, im stuck between buying the £1250 MBP i7 750GB HD 8GB RAM or the rMBP i5 128GB SSD 8GB RAM, i am scared to get the retina because im afraid 128GB will not be enough and not being able to upgrade it.. But then again im stuck because it would be so much faster than the non-retina.. And the nice display. Is it a pain storing media on an external hd togo with the retina? Or should I wait to see the newer models getting announced soon? Helllp! So stuck!
