The iPhone 3G and 3GS in 2017: Why? I'll tell you why!

The iPhone 3G ended production in 2010, and the 3GS was ended in 2012.  So the 3G/3GS series are all 5+ years old now.  But I have one that I keep and use.

Why use one now?  Because these models are still useful phones.  I use mine as a backup phone, for use when friends or family damage or lose their primary phone.

Both models are GSM-centric and have 3G radio chipsets, so they're still great for phone calls.  They have GPS, so they're useful for mapping and navigation.  And you can use them for texting, of course.

They're also inexpensive.  For under $50 you can find a great one that you don't have to worry about losing.  You can keep one as a backup phone, or as a loaner.

Of course, you'll want an unlocked one, so that you can use it with any GSM provider.

The Reasons for owning an iPhone 3G or 3GS:
Super-inexpensive, perhaps $50 for a fine 3GS.A great backup phone if your primary phone is lost or damaged.A great phone for international travel - as all iPhone 3G/…

Why I love my Roomba

The amazing part of the Roomba is how shockingly well iRobot supports them.  You can get a ton of spare parts for them, and it is easy and inexpensive to repair or even upgrade a Roomba.

You read that right: Roombas are easy to work on AND the parts are inexpensive.

That's like buying a BMW, and learning that cylinder heads and alternators are $50 each and can be snapped in within 5 minutes.

I've had my Roomba 600 series for five years. Now five years is a lot of time for a computer technology product that deals with dust and dirt.  Here are the things that I've done so far:

Replaced the battery

After about 3 years, my Roomba's original battery was getting pretty weak.  I replaced it.  Replacing it is a simple affair, taking about 5 minutes.  New batteries are readily available at low cost.

Replaced (and upgraded) the brush head

Evidently I used my Roomba too much in my extremely dirty basement.  My Roomba's original green-colored brush head stopped working well.  I…

Bad Drivers at Intersections

I find it fascinating that many drivers are too dumb or too uncoordinated to stop before the stop line at an intersection with a traffic signal.

A large percentage of drivers ignore the stop line and pull into the intersection - perhaps because they want to "get ahead", or maybe because they want to "see", or maybe because they don't understand the size of their vehicle.

Sadly for these bad drivers, there are sensors in the roadway that tell traffic signals when to change.  If there is no vehicle triggering the sensors, the lights don't change as fast or at all.  Obviously, vehicles already inside the intersection - such as notably beyond the stop line or in the crosswalk - will not trigger the sensors.  Those drivers have to patiently wait for another vehicle to trigger the sensor.


I've seen vehicles wait over 5 minutes in an intersection during low-traffic conditions.  You'd think these drivers would figure it out, but they're so ignorant …

My worst eBay purchase ever
