To Writergirl: I love the hoverbar, I have two, use them in various ways, in the car, kitchen, outside table. Use one in my bedroom, for browsing Internet, reading, and so on; and also for sofa, it does literally hover and is perfect angle.
To Kazmac: there is no scrivener for iPad yet. There is a learning curve, but there are excellent video tutorials on the Literature &Latte website, also on YouTube.
To PDFierro: I magnify text on the MBA, it is usable but still fuzzy compared with the retinas. When I bought mine the 13" retina hadn't arrived, and I didn't want to pay so much money for the first gen 15" with the screen problems etc. I often feel tempted to buy a refurb 15", as the screen would have been tested. But, I think it might be worth holding out for the refresh, hopefully the screen issues will be sorted, battery life might be better, and it will probably have the new faster wifi (I've forgotten what that's called) and that will be important as I would be keeping this computer for a long time. Also waiting because I don't really need the power of the 15" but I don't want to buy a 13" retina and then plug it into an inferior monitor for desk-bound work. If there still isn't a retina monitor when I'm ready to buy, I will get the 15" rMBP.
