With or without contract? Did you try the Apple Store (or anywhere else) first?
I'm gonna try to pick one up on Monday.
Tried the Apple store in Metrocentre - only had 64gb 3Gs. Tried the Apple store in Eldon Square, and they only had wi-fi models.
Got mine on contract. Figured that I was happy paying the £25 a month for 15gb of usage, and as I'm an existing customer, got the iPad for £199.
Really loving it. Only had a wi-fi first gen, so having constant , instant access is really brilliant.
