Projectors only win on upfront price. Over 5 years, the smart board is cheaper, hassle-free, and dramatically more engaging — which directly translates to better student outcomes and (for coaching institutes) more re-enrollments.
Agar projector 3+ saal purana hai aur bulb 1 baar bhi badla hai → switch worth it. EMI par 12 months mein cost cover ho jata hai.
