LATEST DEVELOPMENTS

Perplexity’s Personal Computer now runs on Windows, turning local PCs into AI agents that work across files, Office 365, and the web, aimed squarely at messy enterprise workflows.

Key details

  1. Windows launch: 
    Perplexity expands its Personal Computer agent from macOS to Windows, the dominant enterprise OS.

  2. What it does: 
    Acts as a “digital worker” that can read local files, use apps, and perform tasks like creating docs or updating spreadsheets.

  3. Deep Microsoft integration: 
    Builds on earlier integrations with Microsoft 365 and Teams; now operates directly inside the Windows environment.

  4. Enterprise focus: 
    Designed for work that happens locally on Windows machines, traditionally outside AI’s reach.

  5. Pricing and access: 
    Rolling out to paying Max and Enterprise Max users, starting at $200/month.

  6. Data and safety: 
    Perplexity says it doesn’t train on company data and will always notify users before sensitive actions like sending emails or deleting files.

Takeaway: Perplexity is pushing beyond chatbots, turning Windows PCs into task‑doing AI coworkers that live directly on your machine.

Google hiked AI infrastructure spending to up to $205B, spooking investors and exposing broader funding strain across the entire AI ecosystem.

Key details

  1. Google’s capex shock: 
    Google raised its annual spending forecast to as high as $205B, above prior guidance, mainly for AI data centers.

  2. Spending > earnings: 
    The company is now spending more than it makes, while also facing pressure to keep AI prices low.

  3. Sector-wide strain: 
    Meta, Amazon, Microsoft are expected to show similarly heavy AI buildout costs, worrying investors about profitability.

  4. Nvidia’s massive guarantees: 
    Nvidia is backing AI deals worth about $750B, including $250B in guaranteed debt for OpenAI, seen as a sign of funding stress.

  5. China’s competitive models: 
    New Chinese AI models remain competitive despite limited GPU access, raising doubts about endless demand for US chipmakers and data centers.

  6. Bubble and overbuild fears: 
    Analysts expect overbuilt data centers, many AI startups to die in a correction, and investors are already rotating money out of AI.

Takeaway: AI is no longer just a growth story, it’s a brutally expensive one, and Wall Street is starting to question whether the current AI buildout can ever pay for itself.

Apple’s new Upgrade program lets US customers lease iPhones, Macs, iPads and Watches via Klarna, with lower monthly payments and optional trade‑ins instead of buying devices outright.

Key details

  1. New program name & partner 
    Apple Upgrade is a hardware leasing program in the US, run in partnership with Klarna.

  2. Where it’s available 
    Offered online, in the Apple Store app, and at Apple retail stores across the United States.

  3. Lease terms by device

    • iPhone & Apple Watch: 12 or 24 months

    • Mac & iPad: 24 or 36 months

  4. Starting monthly prices

    • iPhone from $17.99/month

    • Apple Watch & iPad from $11.99/month

    • Mac from $24.99/month

  5. End‑of‑lease options 
    At term end, customers can upgrade to a new device, buy it outright, or return it and exit the program.

  6. Credit check and payments 
    Uses a soft credit inquiry via Klarna (no credit score impact); customers can lower payments with trade‑ins and get 3% Daily Cash using Apple Card.

  7. Not all devices included 
    Entry‑level products like iPhone 16, MacBook Neo, base iPad, and Apple Watch SE are excluded from the leasing lineup.

Takeaway: Apple is turning hardware into a subscription, shifting the iPhone and Mac from big upfront purchases to predictable monthly leases, likely smoothing upgrade cycles and locking customers deeper into its ecosystem.
