Making the upgrade

This time, sensation-seekers, I'm going to talk about the three different bits of hardware in my office that I considered upgrading, and how I walked myself through each decision.

Device 1: Compact digital camera.

Reason for upgrading: A maturing technology. My three-year-old, but highly-beloved, Nikon P6000 pocket camera is exactly the sort of camera I like: small enough to slip into a pocket, but big enough to operate comfortably, and with a sprinkling of advanced features that allowed me to use it as my sole travel camera.

Last year, I did some work for a pal and he generously gave me his Olympus PEN E-P1 camera as a thank-you gift. I soon fell in love with the Micro Four Thir-ds system. It filled a gap for me: I travel a lot and take a lot of photos. and I am hellaciously fussy about the results. As great as my Nikon is, there's no ignoring the facts: it has a tiny image sensor and you can't swap out its fixed zoom for a more appropriate lens ... like Panasonic's magnificent 20 mm f1.7.

With that lens on the Olympus' body, I had nearly the optimum travel camera. It had most of the important features of my Nikon and it wasn't that much larger.

One problem: the Olympus doesn't have a built-in flash. What a pain in the butt! Also, the E-P1 was one of the first Micro FourThirds cameras made and I was eager to see how far the cameras have come after two years.

February seemed like the perfect time to upgrade. Olympus and Panasonic released new Micro Four Thirds cameras. The new Olympus was much like the E-P1, but it had a flash; the new Panasonic was barely larger than the Nikon. After a temporary dalliance with Nikon's fairly awesome P7000 (with its heroic assemblage of mechanical controls), I knew it'd be one or the other.

What I did: I bought an external flash for my Olympus.

Why: After poring through technical specs and advance reviews, I couldn't get excited about either new camera. I was hoping for a major advancement in Micro Four Thirds that would materially improve the Olympus, but I sure didn't see it in the reviews.

The clincher came when I found a couple of intense hardware teardowns and learned that both cameras were using two-year-old image sensors. I want the next-generation component: the one that'll allow next year's Micro Four Thirds cameras to shoot gorgeous photos in low light. And honestly, my big problem with the E-P1 was no flash. Fine: buy a flash. Sometimes you're so enamoured with having The New Version that you forget that the point of the expensive exercise is to solve problems.

Device 2: iPad.

Reason for upgrading: Er ... it's the iPad 2! I love iPad! That's, like, one whole iPad better than my iPad 1!

What I did: I stuck with my original iPad.

It's not that the iPad 2 isn't a huge improvement. Its CPU is a monster. When I ran it through its paces for a review, I didn't test its speed with an engineering benchmark suite. I used real-world apps. One task that took my old iPad more than three and a half minutes to process was chewed up and spat out by the iPad 2 in just 52 seconds. Whoosh!

Oh, yes, and the cameras and the Smart Cover and the gyroscope. I duly tested and wrote about it all. After I filed my review and I started thinking about the iPad like a consumer instead. I recognised all of those features as Nice Things that nonetheless I didn't really need.

But the speed!

Yeah. Well, Apple does a great job maintaining iOS as One Platform, With liberty And Time-Wasting Apps For All. Any app written in 2011 and probably even 2012 will work on my iPad 1. In the end, the speed of the iPad 1 isn't a handicap; the speed of the iPad 2 is a bonus.

Given that I wouldn't do anything with an iPad 2 that I can't already do, I'll wait until next year to upgrade.

Device 3: MacBook Pro.

Reason for upgrading: My current MacBook Pro is three years old. That's like having 125,000 miles on a car. You don't drive it to the scrapyard, but you know that it's entered its zone of Obsolescence.

There's always a faster CPU on the horizon. Tastes change, too. My 2008 MacBook has an ExpressCard slot. In theory, it'd open up a world of hardware enhancements. In practice, I wish it were an SD card reader.

Plus, my MacBook is my daily-use computer. I pound on it for hours a day, seven days a week and I've carried it around the world. Wear and tear is starting to show. The trackpad button hasn't worked since I splashed some coffee on it, and I'm lucky if the battery lasts 15 minutes.

What I did: I bought a new MacBook Pro.

If I'd upgraded last year, I would've had a slightly faster Mac, an SD slot, a working trackpad, and a nine-hour battery. Nice ... but this year, I got a CPU whose architecture is a whole generation ahead. It's clear that Apple's investing heavily in this new ultra-high-speed. multi-channel Thunderbolt I/O port. too. If the standard takes off, my new Mac Book will work with all of the great new high-performance hardware that's going to be released in the coming years. And if Thunderbolt fizzles ... who cares? It's still a functioning Mini DisplayPort.

This is a Mac that will get me through the next three years. That's a big deal given the scale of Mac OS X 10.7 and the OS to follow. I just need to not spill a drink on it.

The past month served as a reminder that hardware should only be replaced if it's about to stop working (whether it's worn-out or just not up to challenges that didn't exist when you first bought it) or if the new one can transform the way you work. Otherwise, you're just being a big, dopey consumer.

I did the smart thing. I thought my way through three potential upgrades, and only made one purchase. lucky me: it was the $2,000 item.
