Hi Synaesthesia, thanks for your reply.
I didn't mention in my first post, but we are a "Special School", so the in-class set up is unlike most mainstream primary or secondary schools. We will have 2-3 iPads (or at least that is the plan) per class of 8-12 pupils. The pupils will not have an iPad each and will often be working on different things at different times, depending on the level of the child. The IWBs are often used as a separate learning device either for an individual child or small groups of children (perhaps with vision difficulties or who cannot use an tablet device) so are very much needed. In addition, the lack of Office or integration with our network would be a sizeable drawback for the teachers. This is a huge shame as I think the teachers would love the iPad and at £260 ex VAT for the iPad 2 they are IMO good value.
Another option would be to allow them to keep the laptops, but simply purchase a very basic tablet to allow them to take photo and video which would be stored on the servers. Most of the lower end tablets run Android? Can this integrate into a Windows network in any way to allow photos taken on the tablet to be stored on the server?
I haven't totally discounted the iPad, especially for SMT, but the downsides to me are that to run SIMS, we'd need to use something like Emerge which carries a high cost. I also wouldn't be able to use SIMS Personnel or FMS unless it was via RDP (or at least that is my understanding), and RDP with a touch screen device doesn't seem the slickest way of doing it. The iPads in class will be pretty much stand alone, without the need to integrate with our existing network except simply having access to the WiFi.
I had a play with the HP Elitepad and they are very iPad like with the quality, but as you say, they are about 50% more expensive than the Acer when you include the dock, keyboard etc, and I don't have the budget for this for all the teachers!
Ho hum.
