You may wish to consider a Microsoft Wireless Entertainment Desktop 8000. I have the 7000, which differs only in that it lacks the backlit keys of the 8000, which I didn't want.
My 7000 is an excellent HTPC keyboard. Lots of dedicated keys for its role as a Media Center PC keyboard. It comes with a seperate mouse but there's also a really small mouse pad on the keyboard itself. It comes with a Bluetooth dongle but would probably work with the Bluetooth in your laptop.
Both keyboard and mouse battery life are excellent - seems forever - and the range is good too, certainly 15 feet. Maybe the backlighting would kill an 8000 a bit though!
I usually drive my dedicated HTPC with a Harmony 1000 remote, leaving mouse & keyboard in a closet with the PC. I only use it if I need to do some serious tweaking but it's always ready for use.
These keyboards are expensive and seem to be drifting out of the MS product line - you might want to see/try one first especially as they are very expensive!
