Apple's Slate PC is available for pre-order today (10 May 2010) after Apple delayed the UK launch of the highly-anticipated device by a month due to unprescedented demand in the US.
Orange customers will be able to choose from four different 'pay-as-you-consume' tariffs.
For £2, iPad owners will be given a day's browsing valid for one day until midnight and capped at 200MB, while a week's browsing capped at 1GB (valid for seven days until midnight), is priced at £7.50.
Alternatively, iPad Monthly 15 costs £15 per month and offers 3GB of mobile data and 750MB of Wi-Fi access through BT Openzone hotspots, while iPad Monthly 25 is priced at £25 and offers 10GB of 3G browsing and 750MB of Wi-Fi access.
Orange is also offering a pay-as-you-go option priced at 5p per MB of data.
According to Apple's website, the iPad will cost £429 for the 16GB Wi-Fi model, while the 32GB and 64GB versions will be priced at £499 and £599.
Meanwhile, the 3G models cost from £529 for the 16GB model, £599 for 32GB and £699 for 64GB. All prices include VAT.
Apple has added a £100 premium for the addition of 3G functionality.
