The best professional laptop on the market

I bought a new MacBook Pro last month, and I’ve been very happy with it so far. The Intel Core 2 Duo processor is a real bonus, allowing the computer to 1……. tasks faster than earlier MacBook models; the 160GB hard drive is large enough to 2……. all of my music, photos and videos; and I didn’t even need to buy an external 3……. – the widescreen 17” display is easy to look at, even for long periods of time.

Another great feature is the 4……. iSight camera; it can be used for webchats, to make video podcasts, or even just to take 5……. photos. Software updates are easy, too: if you’re 6……. – just surfing the Web or checking email – and an update becomes available, a box appears asking if you want to 7……. the update. You just click OK, and it’s done. I don’t even have to worry about security either. Every time I transmit 8……. from my computer on the Internet, Apple’s Safari web browser protects my 9……. information, such as bank details and credit card numbers, using a firewall.

The only criticism I have is the lack of a good 10……., such as Microsoft Word. I had to buy a copy of Microsoft Office 2008 in the end, which cost an extra £99.95 – and that’s with a student discount!
