Summary: Pros +The same G19 you've come to know and love, only with a new color palette. +Onboard memory is a welcome addition, especially for users on the move or with a KVM switch. +Advanced surface materials like Hydrophobic, Dual UV, and Fingerprint-resistant coatings +Improved anti-ghosting key registry +Has the letter 'S' in the title, so you already know it's aweSome.
Summary: I've had the original G19 for about two years, and I love it, but it needed replacement for some time now. This "new" keyboard, however, has nothing new in it. Every single thing: the layout, the indicators, the display, the macro keys are exactly the same. They didn't even bother to update the hub to support USB 3.0. All they did do was make WASD keys a different color, which I hate, since I never play using WASD, so it just annoyed me every time I looked at them.
Pros: Ability to change key colors fast, nice lcd, metal volume control handy
Cons: Just cannot type fast with it, 9 out of 10 times when fast typing capital letters, I press shift+letter and it won't type capital letters, I've got to go back and type slowly which is extremely annoying. win 7 x64
Summary: basically if you can get the g15 get it. Yes its bigger, Yea it doesn't have all the cool features but you know what the g15 is WAY more comfortable and the keys feel way nicer. in fact if i can't get a refund for this im giving it to my brother and then getting myself another g15. i wasn't going to bash this but i miss my g15. this thing costs like 150$ more, you must be crazy if you think its worth it.
Pros: LCD display, Small (compared to g15), customizable backlit lighting, better placement of keys i.e volume (compared to g15)
Cons: gets hot (in fact mine melted part of the plastic. I wouldn't be surprised if this was recalled but then again i may just have a defected one), the lcd can't be flipped down (like g15), price, uncomfortable, plastic palm rest, spongy keys
Summary: I finally had to admit defeat. In spite of spending a lot of time on the phone to a very helpful support person from Logitech (available Mon-Fri in working hours only), and despite un-plugging or disabling any hardware or software that may conflict with it, I was unable to get the keyboard to be recognised by my Windows 7 64-bit gaming PC. Very disappointed, though from what I've read elsewhere, I'm not the only person to have experienced this.
