假如你是李华，你的英国好友Peter看上了两款电脑，想购买其中一台，他给你写了一封邮件，咨询你的意见。请根据以下要点提示，给Peter回一封电子邮件谈谈你的建议。要求:80词左右，可适当发挥。.
要点提示：
Dear Peter,
You're asking me for some advice about buying a computer. Here is my opinion.
The Lenovo Laptop is rated as a five-star computer, so it's more popular than the Dell Desktop. The laptop has a 13-inch screen, and it's smaller than the desktop, so it's more convenient for you to use it anywhere.The Lenovo Laptop weighs 3.2kg, so it is lighter than the desktop and easier for you to take. The price of the laptop is 500 dollars, so it's only a little more expensive than the desktop.
Would you like to order a Lenovo Laptop I'm looking forward to your reply.
Best wishes,
Li Hua
亲爱的彼得，

联想笔记本电脑被评为五星级电脑，因此它比戴尔台式电脑更受欢迎。笔记本电脑有一个13英寸的屏幕，它比台式机小，所以你在任何地方使用它都更方便。联想笔记本电脑重3.2公斤，比台式机轻，便于携带。笔记本电脑的价格是500美元，所以它只比台式机贵一点。
你想订购一台联想笔记本电脑吗？我很期待你的回复。
最美好的祝福，
李华

You asked me for some advice about buying a mobile phone. I advise you to buy a P70 mobile phone. Here are my reasons.

On the other hand, the price of the P70 mobile phone is 5, 964yuan, and it costs you over 1, 000 yuan less than the P70 Pro. What's more, the P70 mobile phone weighs 207 grams, and it is lighter than the P70 Pro, making it more convenient to carry around.
Are you thinking about placing an order for a P70 mobile phone I'm looking forward to hearing from you.
Best wishes
Mr. Wang

你在考虑订购P70手机吗？我期待着你的来信。
