@hperrin TBH the downsides don't seem to bad (Other than the possible colour accuracy). The weight and chunkiness doesn't really matter as I already carry around a Canon 60D w/ Tripods and other gear when creating personal videos (not the newest hardware but does the job). The Battery life sure sucks but pretty much anywhere I go will most likely have power even the Trains in the UK have power for Laptops so long journey's aren't to bad if I were to go on them.
From the few videos I've saw so far people are saying on demanding stuff the battery lasts between 4-5 hours what is really good if that is the case but 2 hours is still good if not. The Trackpad I won't be using to often as I really hate them (One of the main things I hate about Laptops) so I will be most likely getting a mouse that will go along with the Laptop when I am out and about, tbh the downsides seem to be more of what sort of laptop I need as well as it being a laptop, no laptop is perfect unless it can turn into a full blown super computer for games, multiple monitors as well as last all day without being plugged in so I feel they are understandable downsides.
