Wikipedia has a better overview of the place.  I’ll just give you my observations in pictures (the rest, as usual, here).

Long-time foreign residents (and good friends) say there's only 3 things to do in Singapore: eat, shop and visit the rest of Southeast Asia. I wouldn't really mind, especially given their awesome weather.

The place looks absolutely stunning at night.

In Singapore and the rest of the world you can find Corona

Their Financial district didn't appear to have suffered the recession too much. Furthermore, everywhere is spotless.

There is very, very interesting architecture.

The place is almost a textbook case study of multiculturalism. Not surprising given that it was forced on them by the government a few generations ago.

The economy is still going strong.

The place seems to be slightly constrained on the political freedoms front, juding by the level of discourse in the country's media.

I recently flew with Singapore Airlines and have to say the experience was very pleasant.  Even in economy class there was more than enough legroom, every seat had a good in-flight entertainment system, the movie selection was both varied and recent, the service was flawless every time and the meals were excellent in both flavour and presentation.  So unlike the state of airline travel in Europe or, worse, the US.

A special mention is warranted to the on-air personnel and their uniforms.  Unlike Western male-originated attire, their stewardesses actually look like women.  The picture below doesn’t do them justice at all.

Roman Catholic masses were cancelled throughout the city, museums were closed and football matches were played behind close doors (my team, Chivas, tied) to avoid the creation of crowds.  People have been generally very calm from what I understand, stayed home and there is no panic shopping, but the streets are rather empty for a city of over 20 million people (some pictures here).  If you understand Spanish, a great chronicle of the past two days can be found here and here.  The city is not afraid, and people still make fun of the situation from time to time.

Video rentals and video stores were doing brisk business yesterday, and schools are closed until May 6th (May 1st and 5th are holidays anyway).  Military personnel have been handling masks around the city and now everybody is bracing themselves for tomorrow: will people go to work or will they home office (those who can)?

The Finnish media have complained about the slow Mexican response to the outbreak, but they seem to ignore that even the National University (UNAM) doesn’t have the equipment needed to distinguish this new virus from its old, previously known cousins and with the normal flu season just ending, there was no cause for concern.  On the other hand the World Health Organisation has praised the Mexican response.

There are confirmed cases in Mexico, the US, Canada and New Zealand, and suspected cases in France, Spain, UK & Israel (map here).  Deaths have only happened in Mexico, and even there two thirds of the 1200 cases have already been released from hospital.  According to some information in the Mexican media, vaccines don’t work, but antivirals such as Tamiflu do.  Airports haven’t been closed, but there is more stringent screening in Singapore, Hong Kong and Japan from passengers coming over from North America.

There are two different hypothesis of the origin of the virus: one points to it having started in a farm in Texas and then crossed over to the border, the other one points to farms in Perote, Veracruz, Mexico.  None has been confirmed.
