Bizzare that the covers got shipped to Europe first. I thought you folks generally ended up being the last to get things. Kobo's supply chain is certainly full of kinks at the moment.
I am not sure about whether or not I will bother with the sleep cover when or if it ever makes it here. $50 Canadian is awful steep for a cover. I can't imagine paying that and getting one that makes it difficult to carry in my purse. Especially since the fridge magnet trick is working just fine for the sleep functionality.
I suspect I will eventually end up getting a tighter fitting case off ebay. I managed to get a really nice one for my wifi for about $10 with a built in wallet that has stood up to years of daily use. It doesn't sound like the $50 sleep cover will be five times the case.
