I had a lot of trouble finding actual bluetooth (ie no dongle) mice when I went shopping. I got this one, and I like it, but it has a couple of issues:

1. Its middle-button ("click the wheel") is too stiff, so I end up rolling the wheel when I want to middle click.

2. When large amounts of intense data (single large file download for example) are being transferred on the wireless network, the mouse movment is jerky. I don't know if this is the laptop's fault or the mouse's fault.

3. Every once in a while, the mouse just fricking *dies* for 20 seconds or so. The bluetooth is just *gone*. I don't know if this is the mouse's fault or the laptop's fault.

If 2 and 3 are common for bluetooth on this laptop, maybe I didn't *WANT* a pure-bluetooth mouse and should have gotten a dongle-based unit.
