What a great site you've built! I'm hoping to be able to use this in the future. One thing that stands out as a must-improve-upon is the PDF datasheet slider. It's not big enough to be useful for me. The slider only covers 1/3 of the screen and the PDF is too small to read. I can zoom in, but then cannot pan so I still end up downloading the datasheet and reading it on another screen. It would be great if we could properly zoom and pan, or perhaps be able to adjust the width of the slider, then put the PDF links at the far-left. If it helps, I'm running Firefox in 1280 x 1024.
I would also echo the need for more product pictures. If the pictures are accurate it saves a huge amount of time being able to visually narrow the list of candidates.
