Dell now have loads of 'refurb' Mini 10's available from their outlet. The standard spec seems to be priced at £171.31 + VAT though there are some machines with a selection of extras (different coloured covers, built in 3G, Wireless 'N', TV Tuners, Bluetooth, 6-Cell batteries, maybe even the higher res screen?) priced from £181.57 + VAT.
I found one with the "Purple Muse" back cover, 6-Cell battery and built in 3G for £181.57 + VAT, still trawling through the list though trying to decide if there's anything better.
Free delivery and a one year 'collect and return' warranty are included as standard.
It's also worth mentioning that Dell have also removed the Mini 10 from their main site this week. While i'm not saying these are new machines it does seem curious that suddenly there are HUNDREDS of 'refurb' Mini 10's in stock.
