Available online from Amazon and Carphone Warehouse, Vodafone has also announced pricing, with Currys waiting in the wings.
And the price war has started already, with Amazon seemingly beating its own launch price – of £668 – by offering the 16GB machine from a third-party, Prepaymania, for £530.
Vodafone has announced its payment plans, with prices starting from £3 per month for 30 days 'occasional data usage', and a price of £499 on the Galaxy Tab unit itself.
Samsung hopes its Android-powered, Flash-browsing, 7in-screen sporting tablet will be take the fight to Apple's iPad, as Android steps up its attack on Apple and the iOS software.
It seems the initial price listing of Samsung's Galaxy Tab may merely have been a flag in the sand, as Amazon has once again dropped the listed price.
The release date is now set at November 1st – later than we initially thought it might be – and is now available for preorder for £600.
Sharp intakes of breath were audible when the first mutterings of the price were heard, but it looks as if slowly but surely the Galaxy Tab's price tag is falling into line with the iPad.
The Samsung Galaxy Tab, launched to much fanfare at IFA 2010 earlier this month, has appeared on sale for £799 – and that's for the 16GB model.
The tablet has appeared on the Amazon UK web site, and while Amazon has already knocked a few quid off its price, it lists the retail price as £799.
With a 32GB model set to be released as well, we can only assume it will cost a fair more on top of that.
We can only assume the Samsung Galaxy Tab will largely sell through service providers as part of a contract bundle, and therefore at a reduced price.
