After having use of an IPAD2 with IOS5 for a week here are my early conclusions. I may well be wrong on some of the points and am interested in your views or ways around some of the problems and indeed in need for more good uses for them in the classroom.
Sleek interface engaging for children
Easy typing for a touchscreen
Good battery life generally lasting 6-9 hours depending on use
Good screen with good colours although a little reflective in direct light
Good range of educational apps
Good app integration in OS
Great for web surfing with the exception of plug-ins requirements.
Great for reading EBooks
Can be remotely wiped using exchange if linked to an account
Great for instant on research
Expensive £200 more than Netbook for 32gb WIFI model
Need cover with stand to make it portable and useable otherwise you have to hold device as typing whilst flat is difficult and causes neck strain
Expensive connectivity for example connectivity to TV or Projector requires £40 cable.
No USB for flash drives or memory card readers
No locking of own apps, for example if you setup settings in apps bought this could be changed or deleted by students.
No locking of settings - a big issue is WIFI where a student could tether their own mobile to the IPAD and allow the whole class to access full unfiltered
internet. Other examples are password lock settings, wallpapers in fact you cant lock down hardly anything.
Desirable to steal and quite easy due to size
Limited free apps
Pay for apps have to be purchased individually needing multiple apple IDs as you can only buy app once per ID.
Pay for apps have to bought individually at full price not an volume discounts or with site licences.
Limited printing need to print Airprint or need additional software
Limited saving via the cloud, or via Frog which takes a long time to access and upload using touchscreen.
No locking of app layouts students can move icons easily.
No automatic upgrade of apps or IOS without additional software
No flash which is still required for lots of websites such as BBC, MyMaths etc
If you enable restrictions if a teacher wants to take them off all folders and layouts are deleted.
Charging port easily breakable if inserted with wrong way up
Charging multiple devices will need expensive trolley.
Not yet jailbroke so can only install authorised Apple apps, as there are some apps which can get around some of the above.
Let me know what you think, although I am really enjoying the IPAD to use, I just think Apple has overlooked some really essential problems for schools to use them in real life situations. I know you can send out configuration XML files but still the locking down seems mainly geared for businesses which is a shame.
