A mouse on an iPad? Come on, It's like buying a plane but driving it on a highway. Doesn't make sense!
What if the display IS the computer? You sit with the iPad on an easel and use a bt keyboard and bt mouse to "get work done", then you pick up the computer and walk away and it loses its pairing with the bt keyboard and mouse and you go browse the web or read books or whatever till you decide to sit down and use it as a "monitor+computer" again. Kind of like a next gen iMac. I wonder if there will be a gen 2 iPad that is at least 8.5x11 and perhaps .75 in thick that will have usb ports, display port and run OS X? I wouldn't be surprised one bit if Apple was already busy working to make the touch iPhone/iTouch/iPad user interface work as a "skin" for OS X so this would be possible.
If Apple insists on shackling us to a "giant ipod touch" they will get smoked when windows 7, Nokia and Android tablets become available. Sure, there will be a market for a media-only device but people only have so much money and if they have to choose between a netbook AND an iPad versus an Android or windows 7 tablet that can do it all, they will not buy an iPad. Apple is to be congratulated for being first with this. It's good to be first, but it's not good to be inflexible.
I'd hate to see Apple suffer the same fate with tablets that they suffered on the desktop 20 years ago. They almost died once because they were unwilling or unable to adjust their business model to effectively compete with Microsoft. With the iPad, Apple has brought us a stunning new product that can do a few things well. If Apple sticks to their guns and requires jailbreaking to use a mouse or browse the filesystem, stick a fork in iPad. It will be done in 18 months.
I bought an iPad and purchased Pages. I have hundreds of documents in Pages format on my iDisk, on my Mac and on file servers on my network. How do you think I felt when I found out there was no straightforward way to get those documents on and off of my iPad? Granted, this mouse issue is not as critical but it is part of the same inflexibility that almost sent Apple to the trash bin once. Let's hope they wake up quickly this time around.
