Firstly, I purchased the Pure PocketDab 1500 in December 2005 and have been pleased with it ever since. Since the Move 2500 release in August 2011 I was in two frames of mind, do I upgrade or keep my 1500? well, I went ahead and purchased one and guess what? best change of mind I've had in ages. If like me you already own the 1500, then you'll find upgrading to the Move 2500 would be a step forward then a step back. The battery life may only be 14 hours as compared to the 21 hours of the 1500, but that's because the battery in the 2500 is only 1000ma where the battery in the 1500 is 1800ma. But, the one thing that did surprise me is walking around Sainsbury's, where my 1500 would cut out and force me to switch to FM, and then the only station I could receive was a local one, the Move 2500 kept going on digital making the FM side more redundant. This is the very thing that once and for all convinced me that going from the PocketDab 1500 to the Move 2500 was a wise move.
The Move 2500 is smaller then the PocketDab 1500, holds on to the digital stations better then the PocketDab 1500, and is better looking then the PocketDab 1500 which to be fair, the design dates back to 2003 as the PocketDab is the same as the 1000, the only difference is the the type of battery, one used AA the other Lithium.
In a nutshell, if you already own the 1500 and thinking is it worth going for the 2500, then go for it, you won't regret it.
If you're one of those people who is thinking about buying a Pure personal digital radio, and you are unable to decide between the 1500 as it's so cheap now, or the new 2500? I would recommend you spend a few pounds extra and buy the 2500, not that the 1500 is bad, just that the 2500 is a lot better, and so it should be, as the 2500 is the first complete design and performance change since 2003, plus the Firmware can be upgraded (there has already been two since August, I've already updated mine).
At the end of the day, although I owned and loved my 1500 for six years, even though it is quite on the large side compared to other personal digital radios out there, up and till Pure released the Move 2500, the 1500 WAS the best out there, now with the 2500, things have got better, and keeps Pure in the number one position in the digital radio market.
***UPDATE***
I just found out how sensitive the tuner is on the Move 2500, hence the reason why it works in Sainbury's. While fiddling about with the FM side of this radio in my bedroom, not only could it pick up ALL the FM radio stations, it also picked up a station called AHBS CR. Not knowing what this station is I put AHBS CR into Google and it turned out to be the hospital radio station which is about two and a half miles away. I did the retune on my 1500 and not only did it fail to pull in all the FM stations, it didn't even pick up the local hospital one ether.
Forget about the price, forget about the other portable digital radios including the 1500, if you are wanting to buy a portable digital radio, the Move 2500 is now 1000% highly recommended.
