I'd really like to get a PDA soon, but I'm stuck on whether or not to get an hx2700 series or an hx4700 series. I guess I'm just asking how important the extra 64MB of onboard RAM is with Pocket PC's considering I've never owned one (does this limit the amount of software you can use, other than what comes preinstalled?). Ultimately, I think I'd prefer the VGA display of the 4705. Any comments/suggestions would be greatly appreciated. Thanks.
