Just thought i'd share my experience.
After watching the WWDC i decided to take the plunge and get an iPad 2... im not keen on the white one and have an iPhone 4 already so figured the 16gb black wifi only one would be sufficient, had a trot into best buy (derby) and asked about putting my name down for one, was told that they were expecting some stock in the next day and because most people were wanting white i stood a good chance of getting one, they said they would call me if any came in.
Next day came and i couldnt wait, so on my way to town stopped back in, went to the counter and asked if any had come in, they told me they hadnt had the delivery they expected and didnt know when it would be now.... However he did have something that i might be interested in,
He went into the drawer behind the counter and produced a 16gb black wifi and 3g model, it was boxed with all the bits but not sealed, he showed me the paperwork that was with it, basically a customer had bought it the day before and returned it stating he didnt realise that he couldnt actually load programmes onto it, because it was opened Best Buy policy is to sell if for 10% off..... couldnt say no really..... Well chuffed with it.
Out of interest, what PAYG data plans are worth looking at for it??
