I’m using Nexus One without SIM card, and Mifi from Verison in a couple of weeks. I used to use iPhone 3G in Tokyo (sadly, it was SIM locked, I can’t use it in the US), comparing two but it’s hard to say which one is better. Mostly I use default applications like browser, email and maps. Nexus One’s maps is awesome. Especially just I was surprised its car navigation. Email app has a feature that iPhone doesn’t have, is adding a star label. For facebook and twitter, I prefer to use their mobile sites than native applications. Software keyboard is not great, many times I missed type. The shape, weight and feeling of touch are very good. Battery life is not bad. I don’t use it as a phone, at least I can use it a whole day. Monitor is beautiful. No crash, no freeze. It’s a small issue, but I don’t understand the meaning of projecting button. It seems like a Macbook’s sleep lamp, but I’ve never used it as a button/cursor.
Mifi provides wifi access point everywhere. It works for Nexus One and any laptop. I often work at coffee shop, so it’s pretty useful. A bit unstable when is in car/train (connect laptop directly it works well) or using for three machines. One thing I should mention is that 5GB/month is not enough for a heavy user. My usage of this month is already exceeded its limit, I’m a bit worry about extra charge. ($0.05/MB) A nice Verison guy said that never heard about someone who is charged overuse, but it seems I’ll be the one. I think 5GB limitation is pretty enough for usual customers, but for me, like use browsing, skype video chat, ssh, remote desktop, download some applications and also pandora, almost over 10 hours per every day, it’s not. Comparing to in Tokyo, Internet connection is extremely expensive and slow.
Update:
OK, I paid $100+ for that month. Basic plan costs $60, so $40 was extra charge. It seems I used 5.8GB. In short, it’s difficult to keep under 5GB/month with only Mifi for me.
