As a member of the site, I would imagine that you're encouraged to fill in the gaps where you see them. Don't see it? Do it, post your results, and let's talk about it!

The only difference is there's an Illy e.s.e. pod function that is not relevant to pulling a good shot using good beans and a good grinder and a portafilter that's no longer pressurized. It doesn't have a steel housing and may not have the same quality boiler, but let's see if that makes a real difference beyond the satisfaction of having a chromed engine under the hood of a hot rod.
The machine that you reference, the Saeco Magic Cappuccino Plus, is a thermoblock machine. At the very least, this is a significant difference in design when compared to the Gaggias or Rancilios that are commonly recommended on HB as entry-level. One needs to understand the difference between a thermoblock and a boiler in regard to the delivery of ~200F water that is considered one of the foundations of espresso. If you haven't already, I strongly recommend looking at the thread on CoffeeGeek that
explains the differences between a boiler / heat exchanger / thermoblock.
In short, A thermoblock is a hunk of metal that has a heating element attached, and has a small tunnel running through it. The design is such that the heating element warms the hunk of metal, which in turn warms the water passing through the tunnel, and in theory, the exiting water is at the prescribed temperature.
In practice, it doesn't work out as well, at least in consumer-level designs, to which Krups, Capresso, and your Saeco can attest. Simply, the design is poorly implemented; the button thermostats that are commonly used to control the heating elements have a wide deadband. This means that they may click "on" at 190F and "off" at 210F, but that's being generous. Even if the deadband is 199-201F, you still have to contend with overshoot. Turning off power to the element doesn't make the element automatically go cold, just as turning on the element doesn't immediately get to 210F. The result is poor responsiveness, which means water temps all over the board. This has a significant effect on the end product.
It appears that, in your post, you minimize the difference in how water is heated. I'd strongly urge you to try some experimentation and see if you can tell the difference between machines.

Exactly. Thus is the implementation of a consumer-level thermoblock on a machine whose price point is designed to be competitive in a market where the consumers are largely less knowledgeable with respect to the finer points of "water-heating design".
One of the selling points for the Silvia is its boiler. For a machine in this class, Silvia's boiler is big and heavy, which promotes temperature stability. Its 10 oz. brass boiler is larger than the comparable Le'Lit PL041 (brass 7 oz. capacity) or any of the Gaggias (aluminum 3 oz. capacity) The Gaggias compensate for a small boiler by using a more powerful heating element (1300-1400w). By comparison, the Saeco doesn't use a single boiler design. It uses a thermoblock that holds 5 oz. according to literature. Its heating element is 980w. Given the price point, it most likely uses an inexpensive button thermostat, which isn't a problem in and of itself, but does become problematic when paired with the thermoblock.

It may be due to the hour, but I find this last comment to be arrogant. Let's make a deal. You "show me" that you've done some research, and haven't come by just to
seagull. Do some Googling, learn what a thermoblock is and how it differs from a single boiler design with respect to delivering water for espresso. Read some more on HB. Learn about the importance that many users here, place on consistent temperature and stability. Then, let's have a good discussion on the merits of thermoblock vs. boiler implementations.
When you're done with that, we can talk about the inclusion/exclusion of various convenience features (3-way valves, ESE adaptors, pannarello wands, etc.) and how they inflate the prices, and which of them, if any, are truly necessary for producing good espresso.
Then, you "show me" that you've tried any of the other machines in this class (the aforementioned Le'Lit, Gaggias, or Silvia) and describe what, if any, difference you observe.

Given the subjective nature of espresso, you may never be convinced. That's your opinion, and you're entitled to it. If you end up never being convinced, then be happy that your palate finds those two equal, but don't go out and declare that it cannot be so since you didn't find a difference.
I own a Silvia. I've pulled shots on Gaggia Babys, Classics, and Coffees. I've pulled shots on consumer level thermoblock machines. The pump isn't the differentiator in the cup; the boiler is. The best shots on the Gaggias come close, if not equal to the best shots on the Silvia. The thermoblock shots went into the sink after a sip. I'm convinced.
It's not anyone's job to convince you. This site is a wealth of information, and on the relative merits of that information, you make your own decisions.
