Read About Featured Gadgeteer – Evan Koblentz

Name: Evan Koblentz
Location: New Jersey

I’m 29, live in New Jersey, and I write about big-business computing
for a living (mostly for trade magazines.) I don’t have the most gadgets or the
priciest gadgets, just some of the coolest ones. 🙂

On the surface, my gadgets aren’t mind-blowing. The PDA I use everyday is a
PalmOne Treo 650; and I
sometimes take along a USB memory keychain, which has a biometric fingerprint
reader and a MP3 player built-in. I drive around in a Miata, which as far as I’m
concerned is just a bigger, more expensive gadget.

But what really distinguishes my Gadgeteer status is my collection of vintage
PDAs. I own every significant PDA built in the pre-Newton era. (I also was a
speaker on this topic at last year’s Vintage Computer Festival — see Separately, I’m the editor
of Computer Collector, which is a free email newsletter (about 600 subscribers
right now) — see the intentionally primitive site at

Now, most people THINK they know about the history of PDAs, but I’m here to
declare that I spent the past three years studying this, using all of my skills
as a professional journalist. As I’ve come to understand the landscape,
following is a list of the most major PDA developments — and I do own all of
