I went into a new Curry's store last weekend, very nice ... VERY nice ... but as usual, hopeless sales staff with no knowledge or penchant for understanding (not suprising based on what they're probably paid; you're never gonna get IT aware staff for peanuts!).
Biggest fail though, iPad accessories at 2 - 3 times the price of the internet. A £9.99 Amazon Targus iPad case was £25 ... rest my case!!!!
As for the other stores (at least in Nottingham) small, cramped, scruffy, terrible staff, terrible service, terrible price ... I always buy from John Lewis (worth the extra) or the interweb for the VERY best price!
