The discussion centers on the advancements in flash drive technology, particularly in relation to the new Microsoft Zune featuring an 8GB flash drive. It raises questions about the potential for larger flash drive capacities, especially considering Sony's production of a compact 4GB flash disk. The conversation highlights that while technology has progressed, the market dynamics favor high-density chips being utilized in more expensive devices like cell phones rather than in lower-cost MP3 players. It notes that smaller MP3 players function similarly to flash drives, allowing for file storage and playback. Additionally, the discussion points out that larger capacity flash drives exist, but their high cost—such as a 16GB drive priced around $1400—limits their widespread adoption. Overall, the focus is on the balance between technological capability and market profitability.
