The Amazon Appstore's 'Wi-Fi Only' tag on certain large apps (read: Plants Vs. Zombies) has been a frustration for those with consistent access to 4G while they're on the go. I mean, come on Amazon, if I really want to download that 75MB PopCap game, it's my data connection! I'm sure there's some reasoning for this (like reducing the active # of connections on the Appstore's servers), but when you're on 4G, it only makes sense that you should be able to do the things you would on Wi-Fi.
Great news for those of you holding out for that WiFi-only XOOM of your dreams: Costco has moved up its availability date for the LTE-less version of the tablet from April 1 to this coming Sunday, March 27. So if you walk into your local Costco this weekend, presumably the WiFi XOOM will be there to greet you for the reasonable price of $599.99.
But, if you order online, you'll get a couple of perks (even if it does mean you won't be getting your XOOM on Sunday).
