Hard disk requires power to spin the disk and moving parts. By its nature a PDA is always on the move something not really good for something that moves often.
Depending on the PDA there are external memory storage which features an additional memory card that you are attached to the the PDA.
There is an incredibly wide price range for PDAs, but in general, you get more power and capabilities for your money with a PDA instead of a smartphone.
In computers, RAM is used for temporary storage. PDAs, however, use RAM as their main storage. 99% of the apps you install are saved to RAM.
The most common forms of PDAs are Smartphones, palm PDAs and pocket PCs.
Handheld PDAs are available from Amazon. Alternatively you can purchase handheld PDAs from eBay and other online sites new. You can also buy them second hand from Gumtree.
In my opinion, Blackberry and Palm make the most functional PDAs
