i finally decided. will be getting an iPad Wi-Fi 16GB. And i really want NIKKEI web viewer to support to iPad apps on non-Flash version.
weekday morning, i take train Hibiya-line and Oedo-line with NIKKEI and MJ news paper everyday. if NIKKEI has support to iPad, my commuting style will be changed.
why 16GB? yesterday, my friend showed me his iPad 16GB and told me "size is enough by 16GB if you'll use online storage, laptop, iPhone and iPad". why Wi-Fi? i have pocket Wi-Fi :)
