What is the perfect sissy phone for everyday use?

Assuming you had to work within realistic constraints, how would you design the perfect sissy phone (or laptop)?

Here are some guidelines for the hardware:

• It should be inexpensive, ideally around $200 or less (and can be pre-owned)

• It should be easy to modify (e.g. install a different OS on) and not a privacy nightmare

• It should be fairly common, e.g. easy to find and buy off Amazon

• It should have all basic functionality and the ability to access the internet if needed, but it doesn't have to be high-performance

• It should be decent quality and reliable

Those are just guidelines though - feel free to bend them if your imagination calls for it.

Another consideration to keep in mind is whether you're designing a device for Secret or Exposed sissies. Exposed sissies wouldn't mind having a pink glittery phone with a sissy caption as the wallpaper, but secret sissies definitely would!

So to sum up: what model of phone (or laptop) would you choose? What software and apps would you install on it? What other personal choices would you make for it! I'd love to hear your answers!
