Based on user and ISP speed tests this website has a good indication of the internet speeds around the world.

Speedtest.net - World Results

It could be used to estimate if you will be able to upload/download photos or just access email from your country of choice.

Interesting. South Korea on top was obvious, but who would have thought that Lithuania is in 2nd place and countries like Romania and Moldova make it to the top 10!

Well, and the US or Canada are not among the top 15 while, sadly, Argentina (where I'll be the next 2 months) is only #81 in download speed :-(

I'm from Moldova and my brother lives there. Right now he is getting 100mb/s download. It's a normal package in the capital right now. Thailand is far behind when it comes to internet..

Just for laughs I looked up population density and total area for the top 5 and Thailand.

South Korea 100210 km² 491/km²

Lithuania 65200 km² 50/km²

Latvia 64589 km² 34/km²

Andorra 467 km² 180/km²

Romania 238291 km² 90/km²

Thailand 512120 km² 132/km²

Funnily enough Thailand had more unique IP address (at least 3x) from those test than any of the aforementioned countries with the exception of Romania...could that be skewing the results? Add in the land area to cover is at least twice as large as the same group.
