For those of us in the UK that do visit Europe or wish to speak to people in Europe with Google Hangout, Skype etc. this is excellent news, as it presumably is for all Europeans.
EDIT: I speak of personal experience, I can't really talk too much about Eastern Europe people but I have met many people coming from there and I didn't hear any specific complains.
Anyway, the distinction is abstract, and probably has few real world implications, but legal requirements to carry identification, or to register your official residence are among them. It is also an issue that comes up when people are confused outside the US why we have issues around voter ID laws.
Though I can't speak to the ease of relacting between EU countries as an EU citizen, I can imagine that the UK could give the impression of being more open just because you don't necessarily have to enter an imposing building with door buzzers to obtain registration which might feel like you are having to ask permission.
Also, starting with January 1st, 2014, this will no longer be an issue.
On people abusing the system, it happens. Don't worry though, as personally I'm not in a rush of moving or working in Cyprus, especially since the bank tax ;-)
For the UK, and some countries that are not part of the accord, I do need to have a visa, and it is PITA. It usually involved going to embassy, paying some fee, providing documents, convincing the consular you are not doing anything shady, or going to overstay, or whatever. Not fun, especially if you are just trying to do a few days short visit.
I'm an UE citizen, and nowadays moving countries is almost like moving cities (Schengen Agreement is still a little bit different than the UE).
Except for the language, of course!
Btw, whenever I travel within EU one of the first things I do after landing would be to get a PrePay card. In European countries PrePay offers are really good and sometimes better than PostPay contracts.
If anything, I fear that this will favour an oligopoly of the big ones, like Vodafone and Orange, with no real benefit to me, a user accustomed with searching for good local PrePay offers.
Smaller providers will find it difficult to compete now that they are obliged to offer the same level of service, at the same cost, to people travelling throughout the EU.
This ultimately excludes the possibility of cheaper local services: I find it a surprising move from the EU who should act to prevent anti-competitive practices.
or: - forbidding customers roaming coverage and therefore being unable to compete effectively.
Currently I usually buy a prepaid data SIM if I travel to another European country. But this is a bother if you're going to be there just for a day or two.
Most cheap family-run hotels and all hostels have free and good WiFi.
Sucks for those of us who also like higher end hotels for personal travel, though.
I travel without lining up in front of a police guy, showing my passport. A border is sometimes easy to miss.
Took two girls from the US to the meeting point of DE, NL and BE after Fosdem a couple years back. It's .. boring. Taking a picture there seems .. worthless. Yes, more or less just a step away from each of these countries and still - so what? No one cares, you can cross freely.
And boring is good for these things, in my book.
The Dutch-German border was closed, but in practice, outside main roads, there were only roaming border controls. The tripoint of Germany-Belgium-the Netherlands lies on a hill without main roads, so one could cross the border freely there even in the 1960's.
