Should I get an Amazon Echo?

I'm planning on buying an amazon echo dot and I wanted to know whether it is a good Idea for me and will I use it.

I have an iPhone 7 and a MacBook, I don't have any gadgets to turn my lights on and off and to change the heat in my room. I would use it for an alarm, to set reminders, to see what's on my calendar, to make a shopping list, to see the news, sports scores, movie times and the weather.
I watch Netflix a lot and order food from uber eats, just eat and deliveroo. I would also like it to ring people, read my notes, open things on my MacBook and play music.

I just wanted to know if it would do all these things and if it doesn't, what does it do and how well does it work with an iPhone and MacBook and what can I do with it?

Yes

Cancel amazon and order from other sites with prmos and in bulk and electronic coupons and it is so much more cheaper with free shipping and cash back on cried cards.

The only people you can call from an Amazon Echo are other people who have one. I have got one and they're really good.

I have the echo, the echo show and a number of dots. My family uses them all the time. We basically use it all the ways you mentioned and much more. We do not call anyone.

I have the echo and the dot. I use the dot in my bedroom. My husband uses the echo a lot for music. I use them as alarms. I like mine.

If you primarily use them for alarms, wait for the Echo Spot. It is marketed as a smart alarm clock.

Yes, it's good and interesting to use. You are gonna be used to it
