I'm interested in purchasing a sling bag for my Xoom, does anyone know of some affordable, sporty style bags?
I bought this last week: Case Logic 9 Sport In-Car DVD Player Case > DVD Organization > Case Logic. The Xoom fits in there nicely with the Moto folio case on and there is room for the charger, mouse and more. I also picked up the BT keyboard for 1/2 price from Motorola's website. Motorola has all the Xoom accessories for 1/2 off now on their website: Motorola Mobility, Inc. : Accessories : For MOTOROLA XOOM.
In fact, on checking your link I see that it's 50% off the keyboard plus a free mouse! That's $40 for the BT keyboard and mouse together, which looks pretty good value. [Edit] Annoyingly, this offer is US only. The Moto UK site is charging
I bought one of the standard docks on eBay but I foolishly didn't check what ports it had. After all, it's a dock so it must at least have a USB port. Sadly, that turned out to be wrong and, as you say, it doesn't have HDMI. What a crock. It's nicely made and the Xoom fits into it well but in reality it's no more than a stand.
