So I decided I'd rather pick up a 15" high-res i7 MBP at the apple retail store. I phoned Regent St, White City (Westfield) and Brent Cross stores. Regent St. said they didn't have any in stock, fair enough. Both White City or Brent Cross said they had stock (I got them to double check it was the 'high-res' version) but neither would hold one for me (they were told they weren't allowed to at the moment??) So I drive 30 miles and neither store actually has any stock (nor did they claim to have had any at the beginning of the day). It seems the staff who answer the phones don't know that 'high-res' is a variant. What a waste.
