Is It Worth Me Buying The iPod Nano 7th Gen? if So where can you buy them in UK stores?

The current iPod nano is still called "7th gen" by Apple. Some vendors may call it "8th gen" because Apple revised the color choices (along with a minor update to software). The original version and the 2015 version of the 7th gen iPod nano are essentially identical in functionality. They even have the same model number on the back. The one difference is system requirements for the Mac or Windows PC running iTunes to sync it, which is the purpose of that "minor update to software." With the current 2015 version, Macs must run OS X 10.7.5 (Lion) or later and PCs must run Windows 7 or later. Both with iTunes 12.2 or later.

So, unless you are running Snow Leopard or earlier on your Mac OR Windows Vista or earlier on your PC, you can get the current 2015 version of 7th gen iPod nano.

btw, if u can still get the 6th gen if rather have that as it looks nicer as I prefer ios 5!!

Not sure what you mean by that, because iPods (that are not iPod touch) do not run iOS at all. They have their own specific iPod software.

Keep in mind that iPod touch is a handheld computer, expandable with apps, and it has an Internet connection over WiFi. iPod nano is a media player device. It does what it does when you buy it, nothing more, nothing less. No Internet connection. No third-party apps. No Apple Music streaming service. It is better for some things, like exercise. I use it to track my runs. I don't want to carry around my iPod touch or iPhone for running. But don't expect it to do all the stuff that is possible on an iPod touch.

I owned the iPod Touch 5th Gen and felt it was just too big for a music player. I then moved over to the iPod Nano 7th Gen and it is the perfect size for a personal mp3 player. Since then I purchased a JBL Charge 3. Unfortunately, the Nano is useless when synced with the JBL Charge 3. It sounds muffled and the presets available on enhances the muffle. The lack of features and non-existant apps to include fine tuning your music to your listening pleasure would have me look elsewhere. However, for a personal music player, it's bar none the best. If you're gonna portray bar none the best company... put out the best bar none everything! Otherwise, I give it a rating of 2.5 out of 5 for a personal music player and a -2.5 for everything else.
