I wouldn't call it a radical change myself. Tech skills may not have been at the forefront but by the existence of what looked like a potentially custom coded database application in S1 still speaks of vastly more computer skills than any other characters show. Not to mention if I recall correctly there were some videos on there too and whilst Connor may have collated info including the videos from other sources, but he may also have animated them himself possibly based on the other info he'd got...

I'd definitely concede that at the very least they have considerably emphasised his hardware tech skills. S1 was more about knowledge, both explicitly pointed out dino-geekery and more implicit software/coding and research skills.
