Re: [opensuse] Why is RasPi worth more effort than older PCs? or Macs?

For 35 bucks you get a whole computer with the Pi.
For about $65 you get a bunch of auxiliary features like a power supply
case, cables etc, that you really don't need.

But the $35 price includes every thing you really need, including a
fully capable linux distro (three of them actually, as well as BSD).

Up and running in 15 minutes, and, sporting the same processor as
the Iphone 3Gs, it is no slouch in performance.

The Arduino by comparison is bereft of physical ports, even when you
buy the $74 dollar version (seemingly always out of stock),
dramatically slower, still wide less capable than the Pi by a wide

And the distro(s) available for Pi are largely complete, Debian
linux, which every interested 7th grader can manage

But most importantly it WORKS OUT OF THE BOX. Why? Because it
is capable enough to warrant the development.

It has all experimental capabilities bolted on AFTER the fact, rather
than as the principal raison d'etre.
So the kid can blink silly the LEDs on the auxiliary breadboard kits
and build the robots etc, but the basic computer is capable all by
it self of handling real world loads.

And supporting the ARM processor is NOT harder than supporting
the multiple versions of Intel concurrently available.
Its essentially no harder than a recompile of the distro with
different switches.

The problem isn't with the PI, its with YOUR expectations.

You expect the ThinkPad to handle modern workstation loads
and Bloated desktop environments. Why? Well it LOOKS
just about like the machines that DO handle that load.

But the P3 was releases almost a DECADE prior to the Raspberry
PI processor.

The Pi? Nobody expects to put KDE on that, they expect to
run at the command line (although it has a Graphical User Interface
if you want). It has a better chance of running KDE than
that your P3.
