Part of the problem can be that you have them too long. I had fake nails for years and I found letting them get to long was a problem typing. You wind up hitting the row of keys above. I also found that I had to hold my fingers at a lower angle so that I hit more with the pads of my fingers and not the tips. Another problem you can have is the shape of the nails. When they first put them on they did the squared off tip. I like the look but I had them put on just before I went on vacation and found with the square tips I had also sorts of problems operating my camera. After that I got the oval tips. I could push the small buttons with the oval tips.

You will find that there are things you can't do no matter what.
1. Putting on screw back earrings.
2. Squeeze your skin to get a splinter out or pop a pimple.
3. Scratch stuff off like a label etc. The nails are just to thick.

As for picking up stuff it takes practice. Instead of reaching straight down you have to pick up with the pads of your fingers so you have to sort of pick up with a flat hand. It just takes practice. I no longer have them and they did do damage to my natural nail.
