Cover via Amazon

A short note here….but am I the only one who noticed that there isn’t a Windows (or Mac or Linux) Kindle application? I just purchased my first Kindle book and it was wired wirelessly to my iPhone…but I’d really like to read it on my laptop. Granted, I could have bought it through another eBook provider (assuming they had the title) – but it makes most sense to buy Kindle which is portable and will be around for the long-term future…So could someone shout over to the folks at Amazon, “Great job, but…could we please get a desktop app. over here?” Thanks!
