It really really really sucks when the base hardware required to run your software is not available at any retailers (online, in-store, HP direct).
After 5 days of searching, we can say that there are no HP Ipaq 2400 series available in the market.
The earliest we can get them is by waiting for 2 weeks!
These are off-the-shelf Ipaq’s … available at Staples, Compusa, Bestbuy, J&R.
(or, not available, as the case is)
