Great! I recently bought a 14 inch laptop to make it smaller than the big 18 inch laptop that weighed like a weight ball but 14 inch models didn't. I have key 10. I work with Excel spreadsheets a bit, but when I was mobile I quickly got tired of not having it. To save battery, it didn't bother me at all. It would be nice if it were a bit heavier, it's quite light which is fine if that's what you want. It matches the look of my keyboard, flat and slim. My kids became interested in it as a peripheral device, but then they realized it could help them with their homework and withdrew. Backlit keys would be nice, but not if they save battery life. I haven't noticed any latency issues. Operation via Bluetooth. This is priceless for my iddy biddy laptop.
