From the official pi page...

That said, I've been running an rpi as a 24/7 media centre for a few years now, and power supplies have been a problem - two from a (reputedly) reliable source have failed. But they are having to power a disk, and the freeview tuner card turns out to use more power than expected. My current 4A supply seems to be doing better.

In my last job we used them in machines to run the entire system for change machines so they're running the software for the display, running a web server for auditing, controlling the hoppers etc but the PSU purely supplying the Pi so got a lot of experience.

You'll also find if you are using Raspbian Pi and run stress test software that ramps the CPU and GPU up to 100% that on a typical 2A adapter you'll see the lightning symbol come up. It isn't necessarily there all the time but will flicker on and off suggesting it is right on the limit. Maybe its because they're usually made quite cheap with thin wire which is OK at low current but at high current drain there's significant voltage drop due to cheaping out with the cable.

Plenty of cheap sensors and plugins for the pi direct from china, just dont buy anything mains powered.

Most pi stuff is 5v/USB powered so no issues. I have a pile of sensors and stepper drivers. So cheap no worries if you accidently blow them up.

I use Microsoft RDP to remotely connect to my Pi, because it's permanent installed in my garage monitoring various things. I had to install XRDP on the Pi, but it has worked faultlessly since then.

No need to run a full X server and desktop on the pi, when you can just either use cmd-line tools with output redirected through ssh, or you can run an X server on your pc, and run individual graphical programs on the pi, displaying on your pc. X was always designed as a network protocol, so the program can be running on a different machine from the display.

I used to use eXceed, which integrated the remote X windows into the windows desktop. Looks like Xming can do that too.
