（转）新iPad成苹果史上罕见重量厚度双重倒退产品

变厚主要是因为屏幕， 跟lte没多大关系。。。

还好，至少new ipad支持Telstra DC-HSPA+
理论最高下载速度41Mbps比传统3G的7.2Mbps还是快好几倍的。

因为希望用新ipad代替大部分的移动办公所以没有LTE的速度真的就是鸡肋了。 看来还得继续用iphone4的hotspot加MBA好了，

Testing finds HSPA+ speeds still no match for LTE

In what Sierra Wireless called pedestrian mode — moving around at a walking pace — peak speeds fell to 8.5 Mb/s and went as low as 3 Mb/s near the cell edge. In truly mobile conditions — in a car at freeway speeds — data rates dropped further, ranging from 2.5 Mb/s to 4 Mb/s. Similar tests performed on today’s typical HSPA networks — which theoretically support up 7.2 Mb/s — produced speeds in pedestrian conditions ranging from 1 Mb/s to 3.5 Mb/s and in mobile conditions from 500 kb/s to 2.3 Mb/s.

“HSPA+ can deliver speeds approaching 21 Mb/s, but you have to be static under the base station at 3 o’clock in the morning to get anywhere close to that,” Wright said. “I can imagine there are some cases where that happens, say businessmen at their hotel rooms downloading files late at night. But those aren’t your typical conditions.”

亲，其实我和你的观点恰恰相反。我觉得这一代不应该推lte导致外形变重和厚。既然要这一代只满足北美大客户的压力，起码推出全球一款不带lte的3g版本。

起码，没有lte的国家用户，不用为这个cost买单。另外，技术上，支持多频l ...

同意， 应该为除了北美日本以外的国家推一个版本non-lte的版本。

Paramatta,

HSPA现网 大概在6-7Mbps, LTE试验网 35-40Mbps, 差距在6倍左右.

当然, 试验网没有带很多用户,对比起来,占了些便宜.

hmm...from Apple's presentation? the same 10 hrs as ipad 2 on wifi and down to 9 hrs if LTE is used.

A better response is:

Please check the weight of WiFi-only version.

反正不会买4G的版本。。。 LTE对我是浮云。

就算是澳洲的LTE可以用，每个月都会多几十块开销。。。 目前看不出有这个必要。

你用多少流量，每月几十块？

我ipad1用的telstra 的3G卡， 150刀12G有效期一年，一个月才十几刀。

4G卡也不过是150刀10G而已， 当然ipad3我还是会用3G卡

iPhone 4 is thinner than iPhone 3GS while using retina display. So where is the logic that new iPad is thicker than iPad 2 due to feature retina display?

To explain you about the weight of wifi only version, apple use same battery to both wifi and LTE version, so not much profile and weight change you will notice for those two version. Simply because battery is the killer for weight and size. And the bigger battery mainly is to support the LTE.

我现在是WIFI版。iPhone一个月大概能用掉300MB流量。但我这个是3G，换成LTE，速度快了，流量自然消耗得厉害。

我用ipad1，每月流量大概1G，基本都是看看网页，上上qq
我是户外使用比较多的，每天户外使用ipad三四个小时

我不认为速度快了和流量消耗厉害有什么必然关系

浏览网页和下电影又不一样，（在固定时间内）决定你流量的是你看了多少网页
而决定你看了多少网页的是这网页上有多少内容，而不是网络速度。 当然网页打开速度也能影响你看多少网页，不过这个比重很少

除非你因为有了更快的网络而整天用4G网络在线看视频

浏览网页似乎3G也够了？

hmm..your second paragraph lacks logic...If the near doubling of the battery size is to mainly support LTE, why is the wifi version only quoted at one hour more than the LTE one and the same as ipad2? Think about it, if the new display doesn't suck much more power than the ipad2 one, then why wouldn't Apple quote the wifi version at, say 15 hours? Surely it will be an awesome marketing figure and blow all competitions away!

Anyway, if you still have doubt, you can always wait for Anandtech's report, which should be out in about 2 weeks.
