Usually on dSLRs with buttons on the top right, manufacturers place them forward enough to easily reach with your forefinger. On the A500, they're set closer to the camera back where you can't comfortably reach them with either your thumb or forefinger unless you lower the camera. On the cheaper models, Sony puts controls for the ISO sensitivity and drive modes on the navigation switch on the back of the camera. I think that placement works better than the three hard-to-reach buttons on the top of this one.
The Fn button on the back pulls up drive mode, flash settings, autofocus mode, autofocus area, ISO sensitivity, metering, flash compensation, white balance, DRO/Auto HDR, and Creative Styles. But the switch you use to navigate them feels a bit too flat, without enough tactile feedback; I frequently ended up pressing the AF button while moving around the options. (I discuss the settings interface further here.)

While not as flexible of a design as a flip-and-twist articulated LCD is, Sony's tiltable displays are nice for shooting at odd angles. The A500's display is otherwise pretty comparable with the competitions'. If you use Live View a lot, you'll appreciate the A500's fast Live View autofocus, as well as the MF Check LV mode that not only magnifies the focus area but also adjusts the displayed exposure so that you can see what you're doing. While Live View displays only 90 percent of the scene--that's even less than the optical viewfinder--the MF Check LV mode displays 100 percent.
It doesn't burst with novel features, but the A500 has a couple of interesting capabilities. It has an Auto HDR mode that snaps two sequential shots at different exposures and combines them into a single shot with "optimal" highlight and shadow detail. It doesn't have quite as much control as I'd like--you can manually select the amount of the bracket at up to 3 stops in 1.5-stop increments or leave it in auto, but it's limited to two shots and it doesn't save the individual frames, just the combined result and only as a JPEG. But it does seem to work better for extended the dynamic range over Sony's DRO, and the fully automatic setting doesn't override your ISO sensitivity setting as I'd expected. There's a couple seconds performance overhead on shot-to-shot time as it processes and saves the image.
(You can get a complete description of the A500's features, controls and operation by downloading a PDF of the manual.)
The camera stands out from its line mates as the best overall value, but the Sony DSLR-A500's quirky design and interface leave the otherwise nice mid-to-entry-level dSLR lagging just a little behind the rest of the pack.
