Rob Griffiths' dilemma, outlined in MacWorld:
There was my main iMac, which I love. Then there was my “power” laptop, a mid-2010 15-inch MacBook Pro (with the 1680-by-1050 display and a recently installed 750GB SSD), which I love. And there was my “light” laptop, a mid-201211-inch MacBook Air, which I love (and which replaced an older 11-inch Air). So what was the problem?
If it sounds familiar, it is. For several years I was addicted to the 11in MacBook Air. I have owned three of them and two are still around, performing faultlessly. I loved the go-anywhere portability and light weight. Even the small screen I could live with and the latest Air served as my main computer even when travelling for up to a month.
Then I realised that most times when I travel I would take the Air and park it on a desk and there it would stay until the return flight. For day-to-day computing I was becoming more and more content to use an iPad. I began to see the Air as restrictive. In particular, as a keen photographer, I missed a built-in SD card and I felt I really could do with more processing power and a better, larger screen.
Just over a year ago I caved in and bought a specced-up 15in MacBook Pro with retina screen. It became my desktop computer and my travel companion, despite the unaccustomed size and weight. After an 11in Air you really know you have a computer in your bag. But I now have my processing power, I have the convenience and speed of the internal SD card slot and I also value the two Thunderbolt ports (one feeds my old Cinema Display at home, so I really do need that second port). With its 16GB of memory and 512GB SSD drive, the Pro has never been found wanting. And I just love the large retina display which is a delight, particularly when I am stuck abroad for weeks on end. No longer do I have to compromise.
I kept the latest 11in Air in commission. For some months, I would take it on shorter trips and, occasionally, out for walkies in my backpack. But single-day outings became less frequent. While working with two or even more computers is pretty painless these days, thanks to iCloud and Dropbox especially, there are always some small niggles when you pick up a computer that hasn't been used for a week or two.
Eventually I started taking the bigger computer even for short trips. I now use the MacBook Pro exclusively and the Air is sitting in the cupboard, unused but certainly not unloved. Every time I power it up I face a barrage of updates and I am wondering why not to sell it.
Where from here? I have more of less come to the same decision as Rob Griffiths. When it comes time to update in the Autumn I will replace the 15in MacBook Pro with the smaller, lighter and more totable 13in Pro. Like Rob, I've spent some hours playing in the Apple Store and, all things considered, the 13in Pro is just about the ideal tool for someone who wants just one computer for all purposes. My only caveat is that I will wait to see what announcements Apple makes during the year but, for the moment, I favour the smaller MacBook Pro.
