I just received this piece and am disappointed with it.
my first and biggest complaint is that on my dual boot systems (main machine is Win2K and Suse10) it sticks at loading Grub and does nothing unless I press a key so I can't power on and walk away.
my second major complaint is that 4 out of 5 times my keyboard and mouse are not recognised in Win2K. I have to repeatedly press the mouse buttons and key on the keyboard to get it recognised 1 out of 5 (sometimes more) attempts. If I just let the system boot normally, aside from sticking at the Grub loader, then when I get to the Windows login I can't do anything except a cold reset. I've downloaded the latest drivers from microsoft's site but no difference. Fortunately I use Suse most of the time. The moment I plug in my old keyboard, a cherry atx model everything works as normal including the grub loader.
the third annoying thing is in Suse my middle button often doesn't work when I click on links. Usually I have to exagerate the click in an unnatural way to get a response, sometimes taking 3 or 4 attempts to click.
I do like the keyboard for the most part, the qwerty keys are nice, some other gripes are the rather large delete button which is going to take a little getting used to as I touch type and feel my way around so I keep hitting the wrong button when trying to find the key and I also find the left to be too small so I have missed keyed it a few times already today when doing a cut and paste and end up replacing the text with a letter c.
The mouse is a little slim for me. I don't have big hands, but I'm used to the very original microsoft mouse (without the scroll wheel) size of case and find my fingers get a little cramped sooner than I would like, considering I spend a lot of time on the PC.
My rechargable batteries (uniross ni-mh 1300mAh) have been running all day (about 12 hours so far) and haven't shown any sign of loosing their charge. I have a logitech infrared on another machine and normally get around 1-2 weeks heavy use from them, providing I don't hold the mouse button down all the time in-between scrolling. Another set of batteries I use for my camera (uniross - 2300 mAh) have lasted for up to 4 weeks in the Logitech mouse.
I bought this combination to replace my old wired setup, but have been rather disappointed with it. I have tried this on two PCs and a laptop (all dual boot) and have the same problem. All run Suse10 but only 1 dual boots to Win2K, the laptop dual boots to Win98 and the 2nd PC dual boots to NT.
