So, it's the big launch day for the 7-inch iPad-killing machine, the Samsung Galaxy Tab, and the price plans are slowly (and we mean slowly) trickling out.

First out of the blocks is Three, albeit through the Carphone Warehouse with nothing yet official on its site, who has the SamTab available from £99.99 to £349.99 depending on what contract you take out.

For £99.99, you'll be paying £40 a month for 2 years, with 5GB of data a month. For £5 less than that a month, you can get the Galaxy Tab for £149.99 and you'll also get 200 texts.

There are no voice-plans on show from Three at the moment, and the other price-tags, £229.99, £279.99, £299.99 and £349.99 all mix up the contract length and the amount of texts.

O2 is showing the tablet for £599 on PAYG, which is £70 more than you can grab a contract free one from Currys or direct through The Carphone Warehouse.

Update: Orange has also now thrown its SamTab offerings into the mix, although the cheapest you'll pay for the device with it is £499.

For that price you can either pay £5 a month for 500MB of data, £10 a month for 1GB anytime and 1GB between midnight and 4am, or £15 for BT Openzone access on top - all these deals are 12 month ones.

There are also rolling monthly contracts to be hand with Orange, although you'll have to pay upwards of £515 for the tablet. If you don't want to be tied in, Orange is offering the Galaxy Tab at £529, with each MB of data costing 5p, up to a maximum of £40.

Update 2: Vodafone has arrived with its deals. £499 will get you the Tab and there are four monthly rolling plans - £3, £10, £15 and £25.

On the £3 one you'll pay £2 a day for 500MB of usage, for £10 you'll get a Gig for the month, 3GB for £15 and on the top plan you'll get 5GB.
