Buying reality check
Price notes: Google raised the MSRP from $99.99 to $149.99 on 2026-08-31, citing component costs; $149.99 is what store.google.com showed on 2026-09-01. Amazon was still clearing stock nearer the old price, so the two channels are worth comparing while that lasts. At the new price the ethernet port and the Matter controller / Thread border router are doing more of the justifying than the streaming is.
Verified price reads: lowest seen $99.99, latest $149.99 on Sep 1, 2026.
