I use this for everything!!!
I'm a Video editor and bought this product to speed up my work using only one button for a shortcut instead of 3 or 4 on my keyboard (like ctrl+shift+alt+E - just to merge a layer in photoshop. -- now i only press "G7" and its done!) which does add hours to your work when you're working on long projects. But after using it with with Premiere, after effects and photoshop, i started to use it with word and excel too for my letters and invoices and after that i moved on to also using it to start my firefox browser and check my bookmarks and now i even use it on facebook!!! I have lots of text combinations like "Wow you're hot" and "That's awesome" saved up and linked to 10 different buttons and once i click on the comments section on facebook i just push a button and its done! Yes...i know that's very lazy of me. But hey...most facebook interactions are pretty boring and predictable so...
i can't imagine life without my Logitech G13 anymore. The speed of my work has increased by at least 40%!!!
The only complaint i have is that i have to physically push a button every time i switch programs to activate the specific shortcuts. I wish it was automatic. Like, if i'm on photoshop using my presets, the moment i switch to after effects it should recognize it and switch to my after effects presets. But it doesn't do that. I have to press a button. Yeah, it's lazy of me but it would be great if it did that.
