Information About New Technology

 Buying a used laptop can save significant money over a new one, but it also means inheriting whatever wear, damage, or hidden issues the previous owner didn't disclose — intentionally or otherwise. A thorough pre-purchase test, done in person whenever possible, catches the vast majority of problems before you've committed to a purchase. Start With the Physical Inspection Before powering anything on, examine the chassis under good lighting for cracks, dents, or warping — particularly around the hinges, which take the most repeated mechanical stress over a laptop's life and are expensive to repair if damaged. Check that the laptop closes flush and evenly on all sides; a lid that doesn't sit flat often indicates internal damage or a warped chassis from a drop. Inspect the charging port and all USB/HDMI ports closely for bent pins, corrosion, or looseness, since a wobbly port often means an expensive motherboard-level repair rather than a simple part swap. Test the S...

  Like the smartphone market, "best laptop company" doesn't have one universal answer — it depends heavily on whether you're weighing global market share, reliability data, premium build quality, or business-specific trust. Here's how the major players actually stack up across each of those lenses in 2026. The Volume Leader: Lenovo Lenovo has held the global laptop market-share lead for over a decade, and it retains that position in 2026 with roughly a quarter of global shipments. Its dominance is anchored less in flashy consumer marketing and more in its ThinkPad line's entrenched position on corporate procurement lists — the boring but extremely durable business laptop that IT departments trust to standardize across thousands of employees. Lenovo has also moved early and aggressively on AI PCs, integrating dedicated AI processing hardware across its ThinkPad and Yoga lines well ahead of much of the competition. The Reliability Leader: Also Lenovo, Foll...

  Ask "which is the best mobile company in the world" and you'll get a genuinely different answer depending on whether you're measuring unit shipments, revenue, profit, or brand loyalty — and in 2026, that distinction matters more than usual, because the leaders differ across each measure. By Unit Shipments: Samsung Reclaims the Top Spot By shipment volume, Samsung retook the global number-one position in early 2026, driven substantially by strong demand for the Galaxy S26 Ultra alongside its broad mid-range A-series lineup filling volume that the flagship's later launch window left open. Samsung's advantage here reflects its strategy of covering nearly every price tier simultaneously — from budget A-series phones to premium foldables — which no single competitor matches in breadth. By Growth and Momentum: Apple's iPhone 17 Surge Apple posted stronger year-over-year growth than Samsung in the same period, driven by unusually strong iPhone 17 perfor...

 Apple's iPhone lineup in 2026 spans a wider range of models and price points than at almost any point in its history, from the budget-focused iPhone 17e to the camera-and-display-maximalist iPhone 17 Pro Max. Picking the right one now genuinely depends on how you use your phone, not just how much you're willing to spend. The Best for Most People: iPhone 17 The standard iPhone 17 is the strongest all-rounder in Apple's current lineup. It closes a meaningful gap with the Pro models by finally bringing a 120Hz ProMotion OLED display to the non-Pro tier — the same panel technology used in the Pro line — delivering noticeably smoother scrolling and an always-on display capability that was previously Pro-exclusive. Its dual 48MP camera system handles most everyday photography well, though it still lacks a telephoto lens, which remains the clearest differentiator pulling buyers toward the Pro models. Battery life saw a genuine generational jump, and Apple's new 40W chargi...

  Samsung ships more phone models than almost any other manufacturer, spanning from under $300 to nearly $2,000, which makes "what's the best Samsung phone" a genuinely different question depending on budget and priorities rather than a single right answer. The Best Overall: Galaxy S26 Ultra For buyers who want Samsung's most complete experience without compromise, the Galaxy S26 Ultra remains the clear top pick. It runs the Snapdragon 8 Elite Gen 5 for Galaxy (or Exynos 2600 in select markets), pairs a 200MP main camera with a 50MP ultrawide and dual telephoto lenses covering both 3x and 5x optical zoom, and introduces Samsung's first-of-its-kind Privacy Display, which narrows viewing angles to shield on-screen content from people nearby — genuinely useful on public transit or in shared workspaces. The trade-off is a slightly dimmer panel and narrower viewing angles compared with Samsung's non-privacy screens, a deliberate engineering compromise for the a...

 Wireless charging has quietly gone from a novelty feature to a genuinely reliable cable replacement, and the reason is a standard most buyers have never directly researched: Qi2, and its faster successor Qi2.2. Understanding what these standards actually guarantee — and what they don't — is the difference between a charger that hits its advertised speed and one that quietly underperforms. What Qi2 Actually Changed Before Qi2, generic wireless charging pads suffered from inconsistent coil alignment, which meant charging speed varied significantly based on exactly how you placed your phone on the pad — a few millimeters off-center could mean noticeably slower charging. Qi2 solved this by adopting a magnetic alignment system (essentially the same approach Apple pioneered with MagSafe) as part of the official, cross-brand standard. Every certified Qi2 charger now includes a ring of magnets in a standardized position, so a Qi2-compatible phone snaps into precise alignment automatic...

 Most people interact with five or six different wireless technologies before they've finished breakfast — and never think about any of them. Understanding what each one actually does, and why none of them can replace the others, makes you a far more informed buyer of everything from headphones to home routers. Why There Isn't Just One "Wireless" Standard It would be simpler if a single wireless technology handled everything, but different tasks have fundamentally different requirements — range, speed, power consumption, and cost all pull in different directions, and no single radio technology optimizes for all four at once. That's why your phone alone typically runs four or five wireless radios simultaneously, each doing a job the others aren't built for. The Core Wireless Technologies, and What Each One Is Actually For Wi-Fi handles high-bandwidth, short-to-medium range data — streaming video, downloading files, video calls — trading higher power co...
