Ah, the slot machine... a casino staple since the 1950s. What's the first thing you're likely to see when you set foot onto the casino floor? About a hundred or so slot machines, neatly arranged in rows (or columns, depending on where you stand). However, the slot machine's style is going to change in every place you go. Some casinos have proprietary designs, others have stock designs made for anyone who'll buy them. It's sort of like television... most networks have programmes which can only be seen on that particular network, but there are a number of programmes (new and old) which are syndicated and available for viewing on any network that will have them.
...But, they're all the same really. Television shows and slot machines. The mode of delivery with a television programme is the same, no matter what kind of device you use -- it's an audiovisual transmission which you view with your eyes and hear with your ears. Regardless of whether you watch it on a CRT monitor from the '80s, an unnecessarily large LCD screen from 2009, or an expensive 3D TV, it's the same thing. It doesn't matter if you watch on your mobile phone, your PSP, your computer, Hulu, YouTube, CBS.com, Netflix, whatever -- no matter where it is, the programme is still the same audiovisual transmission which you see with your eyes and hear with your ears.
I suppose it's no different from The Incredible Crash Dummies, when you talk about fundamentals. Most of the Crash Dummies would explode when you pressed their impact buttons, but some were more appealing than others. Even though Vince, Larry, Slick, Spin, Axel, Dash, J.R., Wack, Flip, Pro-Tek Slick, Pro-Tek Spin, Chip, and Dent all performed the exact same function, there were ones that I liked better than others. Why? I preferred Spin's indigo colour to Dash's mustard yellow. I really didn't like Chip or Dent, mainly because of their Leno-style cleft chins.
A casino patron might be more attracted to slots with hot girls painted on the casing than an identical machine painted to look like the Old West.
There... I think I managed to stop this entry looking like a criticism of one of the advertisers.
