I actually really like my macbook. Its the base 2015 and although the geekbench results are woeful it actually is a really quick little machine and doesn't really struggle with any normal daily tasks and runs lightroom pretty well.
That being said... They just arent worth the money. They are amazingly portable and it does make a big difference over the MBP but one port and dual core mobile processors... £1299 to start its just insane. Especially if you spec it up to the i7 and bigger SSD its in the base 2018 MBP prices and that destroys it in every measure.
The second hand market hasn't warmed to these either. I didnt think these were worth the money and I paid £650 for mine a year old with apple care and 14 cycles... now they are worth around the £500 mark 3 years later.
What would be more interesting to me is if they made a 15" version, many people would like a bigger display but not necessarily the performance or want to pay £2299 start for a 15" MBP.
