Research carried out by Mike Abramsky of RBC Capital Markets (via apple insider) reveals that up to 20 per cent of those who have purchased iPad tablets last year are likely to buy a new one this year alone.
Since more than 15 million iPad were sold in 2010 (and a few more millions in 2011), this would mean that up to four million iPad owners would upgrade to the iPad 2 over the next few months.
More cautious than many of its fellow analyst colleagues, Abramsky says that around 28 million iPad 2 will be sold in 2011 while others say that this may rise to 40 million.
This could mean that between 10 and 14 per cent of sales may be generated by existing customers getting their second or third iPad 2.
Arguably, this could lead to a glut of Apple iPad on the second hand market although early signs indicate that, like most other Apple devices, the iPad is likely to depreciate less than other competing tablets.
The iPad 2 went on sale online early this morning and will be available in Apple stores and around 10.000 more by this evening (UK times).
Apple is expected to sell more than 500,000 iPad 2 during the first 24 hours of sale, almost twice the amount it sold when it launched in April 2010.
