Apple shipped nearly 12 million iPad tablets in the first quarter of 2012 as the tablet segment enjoyed a very healthy 200 percent rise in sale, while the other three segments - desktop, laptop and netbook - were moribund at best.
Analyst firm Canalyst found that tablets account for around 40 per cent of all client PC shipments in the US, partly due to the "wider choice in content and apps".
Apple, Amazon, Samsung, Lenovo and Asus are the four brands that Canalys has identified as doing well (or really well) in the tablet sector.
The emergence of tablets as a new category over the last couple of years has helped slashed the entry cost of client PC to less than $100.
The second half of the year will see the arrival of the first Windows 8 tablets powered either by ARM-based silicon or by x86 chips from Intel or AMD as well as a wider roll out of Android 4.0 Ice Cream Sandwich and the arrival of Android 5.0 Jelly Bean.
This means that many consumers could delay new PC purchases well into the fourth quarter. In addition, new technology means that we're likely to see new formats (hybrid tablets, ultra portable thin and light, Lapdocks for smartphones) emerge.
