Agreed.

What he's proposing is simply to ignore the rule No 1 of network security: never trust anyone, specially you users.

This reminds me of a place I worked where one of the computers kept getting infected with a virus, even when their files were on regularly scanned network storage. After some time I found out that everytime I cleared the virus (which could not be repaired by my AV, so I had to delete the file) someone that used that computer restored the infected file from a floppy disk, which they never bothered to scan!

I think there's more trouble facing the early adopters. For example, even the hardware isn't all that good to start with. The "modern replacement" of SheevaPlug (mentioned in "hardware is being taken care of") isn't all that good. In fact, this new version, the GuruPlug, suffers greatly of an lack of thermal design. This causes the plug to overheat and start rebooting, until the embedded power supply fails (also because of heat dissipation problems). As a result, to use one of those, the user must also mod the hardware, which creates all sorts of trouble. The manufacturer doesn't even care about it, and keep selling it for those naive enough (like me) to think that the manufacturer should take care of those problems before even starting to sell a product.

I looked at its specs. No way I'd buy that. With 10KS/s you can't even decode audio! The simplest audio files usually are 44kHz. It may be better to build one's own scope with an Arduino (which will get you more geek points), or buy a DSO Nano (with 1Msps 12Bits, and 8 times the sample storage). Minimum Voltage Range Accuracy of 37.5 mV also won't get you very far, specially if you try simple amplifier stuff (which very often can vary only a few millivolts or even only microvolts).

I agree that the Rigol DS1052E is pretty fine for most uses, specially if you have to ask such a question. I have one and it has done everything I needed so far. Even my college use scopes worse than those. If you need a logic analyzer to deal with digital stuff (I think you might, since you're compsci-oriented instead of a proper electronics engineer), you might take a look at the Open Logic Sniffer. It's even open-source, so you can hack it too. The only reason I think you might look for another one is if you deal with RF or something like that.
