A lot of thinking has gone into this and I still have the headache but I plan to install a new 1TB hard drive on my laptop. The thinking revolves around lugging a 99% full laptop plus the associated charger, mouse etc. on holiday with me, the fact that my Galaxy Mini S3 is too small to do anything serious on and the plan to buy or upgrade to a Galaxy Tab 10.1 when my contract is up which will (almost) do the work of the laptop when away. I say almost as I understand the Galaxy doesn't have a USB port so it will restrict the amount of pics and music I can lug around. having said that my grandson is telling me to go for the iPad but that involves the learning curve maybe that I've just read on another thread. Anyway as I don't particularly want a new laptop for aforementioned reasons my new hard drive has just fallen through the letterbox and I'd like to know what I'm facing. The mechanics seem simple enough, I've copied everything I can think of onto an external drive and wonder what will happen when I boot up having swopped drives. I have the Win7 disk which was an upgrade from Vista a while back, other programme disks as far as I can see so will I get a menu come up telling me to do something or what? Thoughts on tablets would also be useful, is there anything with a USB to increase the capacity from a measly 16 or 32GB that most seem to offer and do any take a SIM card when we're away from wifi?
