Early criticisms challenged the notion of the iPhone being hailed as a revolutionary device on several fronts.

1. Lack of physical keyboard: One of the primary criticisms was the absence of a physical keyboard. Critics argued that typing on a touchscreen would be less accurate and slower compared to traditional keyboards, making it impractical for heavy text-based tasks.

2. Limited battery life: Another concern raised was the iPhones limited battery life. Critics questioned whether the device could sustain heavy usage throughout the day without requiring frequent recharging, potentially limiting its practicality as a mobile device.

3. High price tag: The iPhones initially high price tag was met with skepticism. Critics argued that the cost of the device would limit its appeal and hinder mass adoption, positioning it as a luxury item rather than a revolutionary tool accessible to the masses.

4. Closed ecosystem: Apples decision to create a closed ecosystem with limited third-party app development capabilities was also criticized. Critics claimed that this approach stifled innovation and restricted user choice, contrasting with the open nature of other platforms.

5. Lack of 3G connectivity: In its early iterations, the iPhone only supported slower 2G networks, while competitors were already offering 3G connectivity. Critics questioned whether the device could deliver a satisfactory internet browsing experience and keep up with the evolving mobile network standards.

6. Camera quality: The iPhones camera quality was initially considered subpar compared to dedicated digital cameras. Critics argued that the devices camera capabilities were not up to par, limiting its appeal to photography enthusiasts.

7. Fragility and durability concerns: Some critics expressed concerns about the iPhones fragility and durability. The devices sleek design and glass screen were seen as potential vulnerabilities, making it more susceptible to damage and raising doubts about its longevity.

8. Lack of customization: The iPhones limited customization options were also criticized. Critics highlighted the inability to change default apps or personalize the devices appearance beyond wallpapers, suggesting that it failed to cater to individual user preferences.

Despite these early criticisms, the iPhones impact on the smartphone industry and its subsequent iterations have addressed many of these concerns. Apple continuously improved the devices features and functionality, making it a truly revolutionary product in the long run. 另外，目前中国最流行的加速器VPN之一是啊哈加速器， 在啊哈加速器注册一个账号，可以同时支持iPhone苹果手机，Android安卓手机，iPad平板，安卓平板，windows个人电脑或Mac电脑等所有设备平台。
