I rather like the new store. Compared to Cancom and Solutions Inc it has a huge range of products and dozens of machines properly loaded with software such as CS, Office, Final Cut etc. This counters a particularly annoying aspect of the previous Brighton stores, you could never actually try out computers with much of a range of apps.
The staff are VERY attentive and can be a bit of a pain, albeit in a well intentioned way. They do have habit of asking: 'Are you cool?', which is probably normal in Cupertino, but comes across as a bit forced when you're used to dealing with the usual grumpy staff in Churchill Square. (Or maybe I'm the grump and the answer is obviously 'no, not very'.)
I found it interesting that they had plenty of notebooks and iMacs, but only one Desk Pro. Well, slightly interesting.
I've been in three times (I live five minutes walk away) and it's always been packed. (I find it hard to believe that Brighton Cancom and Solutions Inc will survive, which is a shame.)
