I already have a "proper" expresso machine which also does a jug of filter coffee (which is very handy when I host a "coffee morning" type thingy) BUT, I am thinking of getting a Nespresso pod machine which does the hot milk too (the magimix one, about £180)
Why?
I HATE HATE HATE the mess that making espresso makes - the drip tray, the grounds in the sink, washing the scoop, the handly jobby, pain in the arse. I use Illy for it, at over £5 a tin and the fact that the machine is slightly grumpy sometimes causing wastage occasionally means I will probably break even on price per cup.
Pods, whilst bad for the environment, you can get a gadget for that takes them apart so you can compost your grounds and recycle your casing, so that's a potential non-issue if you do that. Google for that, and if you have the Nespresso machine, there's a link to them on one of the Amazon reviews for it. I might come back with the link in a bit.
Also, my mother decends on me for big month long visits here and there (she lives in Australia) and she staggers round like an angry drunk until she gets a latte in the morning. She can't have black coffee because she has a digestive disorder called GORD. She is vile until she drinks this damn latte and I just can't be doing with the faff of shots of espresso, frothing milk etc in the machine I currently have, which to be fair is up for the job but lots of effort.
I like the idea of an easy, mess free option for a quick coffee and lets face it they get amazing reviews. I'm not worried about having to order pods, it has an iPhone app, and if I really hate it and its gathering dust I guess I'll sell it on eBay. But as someone who has a "proper" espresso machine, I can still see the appeal, so if you have the money and are happy to "risk" it to see if its for you, then go for it.
