I think people are confusing what I am saying...
1) paying a service for Push e-mail is not worth it unless it is business critical.
2) Pull e-mail (like on your computer) is usually enough. In fact you can set up automatic retrieval on a lot of phones.
3) SMS only needed if the message is critical
All smartphones are capable of e-mail services. The blackberry connect sw install i posted allows a Nokia E-series phone to be used on a blackberry push e-mail service.
You will find v. cheap phones ( less than USD $50 unlocked) in EMEA and APAC with email capabilities as a standard.
The USA is a uniques market because the mobile operators (AT&T, Sprint etc.) have control of the market. A manufacturer usually has to make a deal with them to be able to supply their phone to the market. The rest of the world (except Japan which has a similar business model to the USA), are pretty much open.
The key thing with blackberries is their market positioning in the USA. The device itself is nothing spectacular. They garnered the market share through the introduction of push-email. Many devices are capable of this but now they have BRAND leverage in the business community.
Calendar functions are also standard in any smartphone, in fact compared to the phones i use (N82, N93i, N93, N95, N81 8GB), the blackberry lacks many features i often use.
In fact i would argue that it has less features than the Sony Ericsson P800 i used to use in 2002.
The key thing is whether you need a full QWERTY, or whether a bluetooth keyboard is preferred.
