I remember being really cool in the early 2k's with a Compaq Ipaq PDA, PCMCIA GPS receiver that slid into the back and TomTom maps in my car. Most devices didn't have GPS then. Damn, they go for a pretty penny on ebay. Have to go dig those things up!
Since we are talking about mobile ports of Tomb Raider, it was also released for the Sony Ericsson range of feature phones too. Albeit in name only because that version was a side on 2D dungeon crawler. I did own that game too but it reminded me more of Roland on the Ropes (Amstrad CPC464) than Tomb Raider.
From what I’ve seen there were some quality ports for the N-Gage. Sega Rally looked surprisingly good from the YouTube videos I’ve seen. But I still don’t regret never owning one since it’s firm factor was, frankly, ridiculous.
