Most children will be pushing you to purchase the latest Mac computer, why? Well they are light and trendy and yes without a doubt work brilliantly. The big downside is they are expensive!
Also remember you will then have to purchase all the Microsoft software that your children will use at their school, sure you can use this on a Mac as well as a PC but it is an extra to the already expensive cost of the Mac!
At http://pc-tec.co.uk/ we recommend that at first you purchase a Windows based PC which is set up to run the Microsoft sofware that schools use.
The costs of the Windows based PC will be a fraction of the cost of the Mac.
