Recently bought the Surface Pro 128GB.
Having been annoyed by the temperament of the touchpad, I bought a Microsoft Bluetooth mouse.
What I've found is that, when copying data over a network, the bluetooth mouse begins to lag.
Using the touchpad/pen is unaffected.
Makes me wonder whether the Wireless NIC and Bluetooth Module are using the same bus and/or whether this is a known issue.

Same issue here with Surface Pro 2 and Wedge Touch Mouse (or razr orochi). Issue does not occur with the same mice on other devices on my network (galaxy tab 2 and two different windows 8 desktops). Really frustrating that a premium product like the Surface Pro 2 does not work properly with basic peripherals with bluetooth mice! This needs to be fixed ASAP.
The same problem here.
Surface Pro 128gb with windows 8.1 + Wedge Surface Mouse + Wedge Mobile Keyboard.
Really frustrating.
I'm suspecting my intermittent laggy mouse occurs when SkyDrive fires up for transfers. This started on day one with the Surface Pro with Windows 8 and Surface Wedge Mouse and continues with Windows 8.1.
I have a Surface Pro and I had the same problem: Bluetooth (Microsoft brand) mouse LAG while downloading from internet big amount of data (video or many web sites downloading at the same time).
I was able to fix the problem today by removing the mouse device and pairing it again.
I don't know if the problem will come back or not (it is working well just from today).
THE PROBLEM IS BACK AGAIN: mouse cursor lag move while downloading video or several web pages at the same time from internet.
I did some testing using my AP which supports both 802.11a/n on 5ghz/2.4Ghz
Using my SP1 and an MS Wedge Mouse, the stuttering/lagging problem only appears when connected to the AP using 802.11n on 2.4Ghz and only when uploading (used a large set of video files for testing to allow the connection to stabilize and allow a good stream not interrupted by "many small files" transfer logic) . The transfers were performed using SMB2 (SP1 using 8.1 with all updates to another Win 8.1 desktop machine).
Please fix it MS!
This is not something that is fixable. The same issue occurs on smartphones, iPads, etc. I can duplicate it on an iPad 3, HTC One, Samsung 700 slate, and MacBook Air. It is simply an incompatibility between 2.4ghz wireless N and bluetooth.
