It's a fairly safe bet that tablets will never suffer from viruses to the same degree as Windows laptops. That's not to say the iPad or Android devices will never be the target of malware, but it shouldn't be a major concern. Of course, you can find antivirus software in the Android Market, but it's pretty pointless. A portable device that isn't vulnerable to the masses of viruses and malware that exist out in the wild is an undeniably attractive proposition.

Which would you choose when going through airports, taking taxis, staying in hotels, and attending conferences and meetings — a laptop weighing between 2kg and 5.5kg or a tablet of about 600g? You'd choose the tablet every time. And it's not just because of weight. The tablet is far superior to the laptop in its ability to work in confined spaces. Need to work in a cab? Tablet. Need to work in the bathroom? Tablet. You simply can't beat the tablet for portability.
A really good tablet will cost about the same as a low- to mid-range laptop. So you're immediately getting more for your money. But now factor in the price of an extra battery and software for the laptop and you can see how quickly the cost can add up. Tablets are quickly becoming one of the most cost-effective office tools available.
