Gorilla arm alvin June 15, 2015 - 9:28am

I just stumbled onto this old article about “gorilla arm.” The question that comes to mind is, “Why did Microsoft release touchscreen PCs if designers and testers were aware of these problems?” (Surely anyone who used a Touchscreen PC for any period of time would have known about this.) My guess is that the decision was driven by the sales/marketing team, not by designers and engineers.

How to stream audio to multiple speakers from Mac, iOS, Android alvin April 12, 2015 - 11:44am

If you want to stream audio output to multiple speakers from your Mac, PC, iOS or Android device, I can tell you that this DIY article is spot on. Based on that article I just did a very similar thing, with good results. The only caveat is that the volume knob on the Lepai LP-2020A+ is very tight, and only seems to work in certain positions, but other than that, the approach works as advertised. I went with the Micca MB42 Bookshelf Speakers for $59, but in retrospect I wish I had tried the smaller Micca COVO-S Compact 2-Way Bookshelf Speakers.

Apple profits from PC sales

Apple has more profit from PC sales than the next five Windows PC vendors combined. (Image from asymco.com.)

I appreciate this. Business people should think in profit, not revenue, but most state revenue. At my software firm, our revenue was only $2M annually, but our profit approached 25%. That's the same as a $10M/year firm with a profit margin of 5%, with a lot less risk.

The Apple Tax - $299 on a new MacBook

Apple's recent announcement that Mac Java support is deprecated inspired me to look at the so-called "Apple Tax" -- the premium price tag you're going to pay when buying an Apple computer, whether that be a MacBook, MacBook Pro, iMac, or Mac Pro instead of a Windows PC.

I just ran a comparison of a base model Apple MacBook versus two different Dell Windows notebook PCs, and the numbers are pretty scary:

The Apple Tax on a base MacBook is a whopping $219 to $299
more than faster, better-equipped Dell notebook models.

Entry level MacBook and PC prices

I haven't been in the market for a new laptop until recently, and I have to say, wow, I didn't know how much the prices had fallen in the PC laptop market. The entry-level PC models make the MacBook prices seem pretty outrageous.
