Gotta love the way how people end up branding people with a different use case than theirs as outright idiots ..
I have the 2015 rev 1 rMB (switched from a 2014 13 air).
My use case is 90% browsing when at home.
Maybe 5% on spreadsheets and 5% for watching a movie while travelling.
And it fits that need far better than anything else I can find on the market...
The screen is far better than the MBA, so is the keyboard
(After using this KB for a few weeks, the KB on the work laptop on which I am typing this feels as if I am prodding on a mushy porridge bowl)
Also totally love the fact that I can charge it with pretty much any powerbank (I brought a cheap Xiaomi 20AH battery pack for it) whenever I want!
I don't really experience any slowdowns although the i5 MBA felt a little faster to scroll on heavier webpages.
The only other gripe I have is that the wifi antenna is the rMB is somewhat weaker than the MBA
As for competing windows products, Windows ultrabooks are horrendously overpriced for whatever reason in India (where I live)
MAcbooks on the other hand are priced more or less at par with the US prices (esp if you wait for a good online deal- The rMB cost me ~1100 USD equivalent, the newer XPS 13s on the other hand goes up to 2000USD or more
Even the Asus UX 305 ends up being over 1000+)
I guess it is probably due to the fact that a) there is a very limited consumer (not business) market for premium windows laptops here...Majority of budget buyers end up buying the 500USD equiv laptops form Acer/Dell/Toshiba/HP etc
b) Whatever little market that does exists for premium windows machines is split between the major manufacturers
Thus the volumes end up getting so low that they can't really price them well
Oh, last but not the least, I was easily able to sell off a 4 year old 11" Air for 50% of the original purchase price.. No prizes for guessing what I would have got for a 4 year old XPS 12 or imilar (if at all I could sell it)
