I'm a Windows P/C user, that about three months ago purchased an iPad. I love it and have found very few things that it won't do. It has opened up so many more opportunities to me. But I have one question. When you use the copy command in Windows the info can take up memory. If the copy is large a lot of memory can be used. Of course you can clear this memory buffer so that performance does not lag. What about the iPad? I do not do a lot of copy & paste but if I copied a large picture or something else does it also take memory and if so how, short of rebooting, do you get that memory back? My iPad seems to run as good as the day I bought it but I was wondering how Mac products handle this copied stuff. Thanks for any advise you can give.
