Tesco have put the Dell Streak on their website on Pay As You Go for just £319.20 which is a good £80 less than a sim free price direct from Dell and cheaper than O2 currently charge.
The Dell Streak is not exactly the smallest device with a massive 5 inch screen so not ideal as a day to day phone device but as a tablet is has to be one of the best and now runs Android 2.2.
Looks like when it comes to Tesco and savings on a smartphone…. every little helps (sorry I could not resist)
