Pros
Cons
戴尔的Venue 8 Pro毫无疑问是一台优秀的平板电脑。戴尔利用英特尔Cherry Tail平台中实现的性能让人惊喜。
搭配4 GB双通道内存的配置保证了相比许多竞争对手的明显性能优势。搭配Windows 10专业版和64 GB高性能eMMC闪存,Venue 8 Pro十分适合日常工作。
它的高分辨率屏幕并不出色,尽管提供了锐利的显示和丰富的色彩,它的亮度只能算一般。平板的接口十分少,用户需要购买拓展坞。而缺少键盘底座让它无法作为变形本使用,特别是如果底座中提供第二块电池,将可以缓解它电池续航时间较短的问题。
整体上,戴尔Venue 8 Pro的整体表现优秀。正在寻找小巧而高性能的Windows平板电脑的用户可能选择不多。基于酷睿m处理器的变形本,如微软Surface Pro 4,提供了更强的性能,不过相比也更笨重(当然也相比这台仅售450美元的测试机更贵)。
我们目前最大的希望就是这台新机型可以尽快上市销售。
