I got the bluetooth Arc Touch mouse and it's great, I have a sleeve for my SP3 which has a front pocket and with the arc mouse folded flat it's perfect. I ordered the wireless display adapter from Microsoft, this device has proven to be the elusive unicorn. I checked my local BestBuy online and it showed they had it, went down there to find out it just showed up in a delivery and nothing has been unpacked but the rep took my name and number and would call me later that day. Got a call back and there were none in the shipment; I kind of think they were in the shipment but someone ran back and brought them out and they got sold right away before the guy could grab one for me so he just told me they didn't show up. When I was there he said the manifest showed there were 2 delivered, for some reason they are getting very few delivered. He also informed me the website status is wrong almost half the time. So I called the local Microsoft Store in the mall nearby, gal told me they had them in stock so I went there after work. Walked in and the guy told me they haven't had any for a few days and the number I thought was to their store is actually a call center and they don't see individual stores inventory (ticked me off because I sat in rush hour traffic to get the unit... plus I hate the mall). So I'd save yourself some time driving around and just order the thing online. I'm in the Bellevue (Seattle) area.
