Apple doing everything to make the event memorable
Sending out an invite with a unique remake of the Apple logo is a brilliant idea and an epitome of creativity. A lot seems to have been put into ensuring that this event becomes a major talking point, for the next few months.
If there was a rumor that a new product was going to be launched, anyone would most probably halt any purchase plan, awaiting the release. If the company is aware of these numbers, then the first step would be to launch the new Macs and iPads, in the shortest time possible.
