All the advantages and disadvantages have already been repeatedly listed. The only thing I can add is how to make the PSP kit as economical as possible. Instead of memory stick duo cards, it is quite possible to use microSD class cards + an adapter, it will come out much cheaper. As practice shows, a 16Gb memory card is more than enough, you can even limit yourself to 8Gb. It doesn't make much sense to buy Crystal Elite accessory kits, especially if you don't intend to use UMD discs. Headphones from this set are not particularly comfortable. They fall out of the ears and the sound is not very good. The sound will be much better from inexpensive plugs. The remote control on the headphone wire is not needed in practice. It makes little sense to buy a TV connection cable, because. the graphics aren't great, and it looks even worse on a bigger TV, plus the connection is analog. A strap and a set of interchangeable joysticks are also not particularly needed. And finally, you can use any noun. miniUSB cable from a camera or camera to connect to a PC. Of the mandatory, you need to buy: a protective cover, preferably made of plexiglass (already saved from 1 meter), a film on the screen, a memory card of a suitable size and a miniUSB cable, the rest is up to you.
