The Logitech Illuminated is nice. Same with the Razer keyboards. But I don't think that's what you're looking for since you want to move away from the flat strokes of the laptop keys. Being honest, you'll really want to stay with thin keyboards. The transition is mind boggling from thin to regular. It took me two weeks to get used to my keyboard when I was only using a half thin, half full keyboard.
The Illuminated is the best for general use. There are some Mac ones, but I think you have a PC. Razer is best used for gaming, which I'm not sure you'll like as much. It's targeted specifically for gaming, so you'll lose most of your media keys.
If you want to move away from low profile, a good keyboard is the K350, or the Logitech Wave, which is the K350's wired partner. Both are great, but no illumination and the learning curve is huge. You'll feel VERY awkward trying to go back to the laptop keys, or any other keyboard in general.
Microsoft boards are generally low profile, so Microsoft to Logitech will be hard.
G15 is not recommended for general use as much as others. Again, it's catered to the gaming communities. Most keyboards are. Regular keyboards, as long as they don't suffer from ghosting, offer better functions than gaming keyboards, except for maybe bindable keys.
If backlight is really that important to you, go with the Illuminated Logitech Keyboard.
The reason I love the wave keyboards is because of the amazing wrist rest. Best. Idea. Ever. I still want to look at Microsoft for all its media buttons though.
Unless you game a lot, there's no incentive to buy gaming boards, except for the extra programmable buttons.
Mac Series Logitech Keyboards is DiNovo or something I THINK.
It looks like I just threw random ideas in together. Oh wells
