CompUSA is currently offering a $100 trade-in rebate towards any new Pocket PC when you bring in your old PDA. The offer doesn't specify what kinds of "old PDAs" qualify, or whether you'll have to part with it in order to get the rebate (we assume not). That can net you a 32MB Audiovox Maestro for $199.99 or a Compaq iPAQ H3835 for $399.99 (which includes two additional rebates). Need a keyboard to go with the iPAQ? Get the Stowaway for just $49.99 after rebates.
