The 20 Most Innovative Products of the Year

Innovative Products, #11-#13

11. Pioneer Inno

Satellite radio reaches a new level of portability with Pioneer's $299 Inno XM Radio receiver. Earlier devices simply recorded snippets of radio shows. This is a real live-radio receiver that can record and store songs, too, and it lets you bookmark tunes you want to buy later. (Samsung's Helix, which we didn't test, is a nearly identical model.)

12. Farecast

Lots of sites help you find the best airfares if you're buying tickets right now. But what looks like a great deal one day can seem overpriced the next. Farecast tracks fares over time, telling you whether prices are likely to go up or down over the next week.

13. Sony BWU-100A Blu-Ray Disc Rewritable Drive

Sony's $750 BWU-100A (check latest pricing) wasn't the first internal Blu-ray Disc burner we saw (that honor went to Pioneer's $1000 BDR-100A), but it offers the most complete package at the best price, and unlike some others it can write to both 25GB single-layer and 50GB dual-layer discs.
