Well, lets start off with a few good things about MS Paint. Oh, wait! There are none.
I think Microsoft Paint is completely useless compared to programs like Adobe Photoshop and GIMP, and it hs almost NO features that you can use to make your delightful picture... delightful.
From there, we move on to the freagin pixels. No matter what you use or how you use it, your picture will always look so pixelated, and for me, that is just not acceptable. For others, maybe not, BUT THIS IS BLASPHEMY. Like, even after your done finishing your awesomely awesome-sauce picture, and you click to save, as soon as you press your finger on the mouse to click on that, oh-so-precious 'save' button, your picture automatically SCREWS UP AND GOES ALL FUFFLED like. That is not a good thing.
Even though all these points are listed down, and I bet there are many, many more to be founded by others, we still use MS Paint. Or... at least, some of us do, but all that behind us, I still use it... and Im finding a way to deal with its crappy features...

GOOD LUCK TO YOU ALL IN YOUR FUTURE ENDEAVORS
