The iPad (and its new big brother the iPad 2) have not really had any decent competition (apart from Motorola's Xoom) but this is set to change with the launch of Samsung's Galaxy Tab 10.1 - in just over a month from now.
The Honeycomb-powered, 10.1-inch sized Android tablet will be launched in Australia mid April and the only downfall is it will be exclusive to Vodafone at launch. There will be two pricing options for the Galaxy Tab 10.1 with Vodafone - a $729 outright purchase which includes 6GB of data with a 3 month expiry, or a $259 up front payment and $39 per month for 12 months (which does include 1.5GB of data every month).
Compare this to the original Galaxy Tab which had the outrageous $999 outright pricing this is a great change for Samsung and it will allow them to really take pot shots at Apple's iPad 2. The only downfalls now are the data use and speed in which Vodafone's network is notoriously known for not providing, but people with Wi-Fi networks at home should be fine.
