Onyx Boox Go Color 7 (Gen II) vs BOOX Note Air4 C

Buy the Go Color 7 (Gen II) if you want a light, pocketable color reader you can carry all day; buy the Note Air4 C if you need a large canvas for note-taking, PDFs and split-screen work. The Go Color 7 is a 7-inch Kaleido 3 reader at about 195 g with Android 13, 4 GB RAM, 64 GB storage and a microSD slot, but the stylus and cover are sold separately. The Note Air4 C is a 10.3-inch color ePaper tablet with 6 GB RAM and a bundled stylus, so it writes out of the box, though at roughly 14.8 oz it is a desk-and-bag device, not a pocket one. Owners of the 7-inch Boox line praise the portability and front light; larger Note Air owners praise the writing space but note the weight and slower color refresh.

• Choose the Go Color 7 (Gen II) if you read on the move and want a one-hand color eReader with a memory card slot.
• Choose the Note Air4 C if you take handwritten notes, mark up PDFs or want a bigger screen with the stylus included.
