Well people probably don't mean that they copied it directly because that'd be impossible. What they probably mean is that Microsoft, knowing that Apple are working on a new tablet, decided to unveil there own at CES which is exactly what they did and that's business. Nothing wrong with it.
The moment MS knows about this device made by Apple, Apple should have a big lead. MS stated dozens of times, especially Bill Gates back when he was CEO that he thinks tablets are the future. Check this 5 year old article about Bill Gates and his tablet PC
MS worked on this probably longer than Apple. Probably since 2001 or whatever. But hey, it is cool to say MS copied again.
There once was a great sig here, but it got killed.
A moment of silence would be appreciated.
