很无奈, 本来IPAD是个很风险的东西, 结果大热; 相反, IPHONE系统应该很成熟了,
结果出了大问题.
我想了一下, IPAD这个东西实际很奇怪, 他没有专门的FUNCTION, 你拿他画画, 看书,
玩游戏, 看书, 或者实在不堪看毛片, 所有的功能都是你定义的. 但是由于IPAD的
新颖性, 你可以用很不同的方法实现你定义的功能, 比如, 躺在床上用各种体位看
毛片. 于是我们很满意.
IPHONE就不同了, 功能已经预先定义好, PHONE, 如果这个出问题, 整个系统会受到
很大的怀疑, 至于那些锦上添花的东西, 由于没有下层建筑的支持, 就成了很虚无缥
缈的东西.
在长叹一个. 还是跟乔总的桀傲不驯的性格有关系.

No logic. iPhone is much more complicated than iPad.
What's in iPad? Bigger room with fewer components. Where is the engineering
challenge?

ipad has no competitors so far.
ip4 is in hurry given the antenna issue. i think it's because apple see
Android pressure. they must hurry up to lock the users.

apple made a successful brain-wash: users are thinking ipad is different
from netbook.
in my view, it's just an enlarged itouch with 3g enhanced. there's little
innovation inside.

No. I believe it is just not enough QA and Apple got too confident with its
industrial design. Aesthetics of industrial design often win over pure
engineering. But WTH, it is part of Apple's core value. Apple did make great
stuff before. Apple also made beautiful failed products before. This is
just Apple.

great
Not really. The signal loss is not outrageously severe compared to HTC's
Nexus One. 24db vs 17db.
What makes this problem appears shocking is iPhone's signal bar covers only
23db with the last 4 bars. So if you had only 4bar or barely 5 bar to begin
with, you will see the dramatic effect of bars disappearing one by one.
Even if they had the similar level of signal loss as HTC's phone, you'll
still see a loss of at least 2-3 bars.

but QA should have found that it you touch it in certain way, you can lose
connection, and the data speed is dramatically reduced?

xuansu (xsu) 于 (Thu Jul 1 02:19:52 2010, 美东) 提到:
they must have deemed it an acceptable compromise when the antenna design
offers much better signal clarity when the signal strength is not reduced
below connection threshold.
In fact, had they changed how the signal bar is calculated before releasing
the product, nobody would have noticed anything but much clearer calls and
better range than anything that came before.

ft, you think 7dB different is not big? it translates to 5 times difference
in signal strength, dB is in log10 scale.

xuansu (xsu) 于 (Thu Jul 1 10:34:58 2010, 美东) 提到:
difference
7db at the low end isn't significant in the big picture. probably just
means a mile or two less from the tower. plus, iPhone's much longer antenna
compensate for the lower signal strength

P836 (大同利益) 于 (Thu Jul 1 12:37:29 2010, 美东) 提到:
I have to say that you definitely are not a person working in communications
area, not even EE area. You have no idea about the signal requirement for
communications. No idea on S/No, etc. But you drew your assertive
conclusions so easily -- is the rest of the world fool or are you?
I feel sad for those engineers who fight and work very hard for only 1- 2 dB
improvement in system performance.
You are not only an iPhone fan but an i-diot fan. :-(

if you yourself know anything about signal noise ratio, you wouldn't have so
quickly dismissed apple's design choice as defective.

Actually Apple is very strong on the tech stuff. They really know what
should be under the hood and how to make them work. Their recent A4 chip
is a strong proof of their ability beyond board/system/OS design.

ipad 和 iphone 一代一样，都是划时代的产品。
之后的后续产品都只能说是改进而不是革命。。。
本质上来说，ipad的成功是因为用手指取代鼠标和键盘，这绝不是一个简单的改变。
所有的现有的操作系统和软件都要重写。。。

do you know the typical cell size in urban area? a mile or two. So "a
mile or two less from the tower" moves you from cell edge to right in
front of the tower. 7dB difference is 7dB different, there is no such
saying as lower end or high end, as a matter of fact, at the high end, 7
db less might be ok, for example, drop from 100 dB to 93dB is not a big
deal. (numbers are exaggerated but you get the idea).
