Red laser app (barcode scanner) is completely pointless but pretty cool.
Eh? What’s pointless about being able to zap a barcode on a book, cd or DVD at the moment you spot it in the shop, get alternative pretty much straight away, and be able to buy when you want. I scanned Blonde Redhead’s new album in HMV last Saturday, marked up at £14, got an alternative price of £6.48 straight away. Yes, I could Google it, but the scan is much, much quicker. Amazon have adopted the scan mode as well.
Live Earth HD is a really nice app, UK Map with free 1:25 and 10k OS mapping is very good, CoPilot Live works well for £20, Stanza, Kindle, ereader are all good for ebooks; it’s worth having all three, as well as iBooks because some books are restricted geographically by your credit card address, and Kindle and iBooks gets around that.
