To be honest I'm glad I'll be without the G amp for a little bit - I dont think I would have ever really put the machine through its paces properly if I had the Ti to lean on, lol.
First impressions were pretty good, although the i5 is just dreadful in Lightroom. I'll probably only hang on to the 13 until a 14 or 17 is released following the same ethos as the 13. Its a shame though, if they had been able to shoehorn a true i7 quad in here, it would be quite literally perfect to me. Just the right amount of garish lighting to satisfy my fanboy, and slim, light, sturdy, EXPANDABLE and powerful enough to dethrone the defacto rMBP as my laptop of choice. Right now its an also ran due to not having a built in SD card.
I would have taken an 840m or even *gasp* Iris in here if it meant this chassis could carry a quad. The screen is small enough to make 720p gaming acceptable and either Iris Pro or 840/850 would have excelled there.
