The tech buying guides that actually name a winner.

The smart glasses market splits sharply at the $200 mark. Below $200, you get 8MP cameras and core AI voice features; above $299, you pay for 12MP sensors and advanced lens technology.

The smart ring market spans from a $40 entry tier to the $499 premium ceiling, but spending beyond the $209 mid-range primarily buys software features rather than new hardware capabilities.

Match the tablet architecture to your major to avoid paying for performance your battery cannot sustain.

The $39.95 tier secures reliable microphone hardware. Paying $79.98 introduces real-time adaptive noise cancellation and Dolby Audio.

Your choice depends entirely on your primary subject matter. Action capture demands rugged waterproofing, professional work requires a full-frame sensor, and learning the basics only needs an affordable lens bundle.
