Here's a quick testament about the Philippines. https://www.youtube.com/watch?v=f-tKE812-ZY
Internet is OK at best. I have an internet line from three different providers, all three have been offline at the same time more than once, and speeds drop to dial-up or worse on my main line at least 2-3 times a month for hours at a time. I've observed this at multiple locations.
"Brown outs" are pretty common, get a UPS.
Good quality electronics and computer components can sometimes be tough to find but a quick trip to Singapore will sort that out.
Shipping can be a nightmare, I've waited months to receive packages in some cases.
Any involvement with any government run entity is a nightmare. I got a parking ticket because I accidentally left my motorbike in a non-parking space. I went to the office when it opened at 8AM to pay it. It took me 4 hours to pay the parking ticket.
Traffic is so insane and rules are so rarely enforced that I stopped riding my motorbike.
I'd suggest avoiding Manila, as all the Taxi drivers want to rip you off or haggle a fare with you instead of use the meter (same problem in Bangkok, Thailand). But there are plenty of cities in PH that don't suffer from that problem (Davao for example, is great).
Last but not least: Don't drink the water. Be careful where you eat. Food hygiene and quality standards might shock you.
But, that's about all the bad things I can come up with, and they're all manageable. The people are great, cost is low, and fly to nearby countries cheaply and quickly.
Internet?? Well yea! Depends on the area you're in. I have 50mbs on a fiber connection and no major problem so far. Except when I travel to nearby islands, then internet connection can be really bad.
