I have an A1...
Plus side: GPS
Minus side: could be faster, needs WiFi to update GPS maps in real time, buggy factory installed software, neither camera has a flash.
Looking into rooting it: to raise the CPU speed, to drop the Chrom-ish browser from being default and to remove buggy Lenovo app store software.
Cannot drive very far from a WiFi connection until Google Navigation starts having trouble. Maybe a few hundred yards. Using FoxFi on a DroidX2 (DX2 is used as a hot spot) to link DX2 with my A1 seems to be a good method of using the A1 as a GPS instead of the DX2. Screen size of A1 is roughly 3x the DX2.
The Lenovo App Store, when launched, proclaims there is a newer version of the Lenovo store app available, then when you accept downloading that newer version and you try installing it, upgrade always fails to install (I following all the instructions, naturally).
Buggy software is that Lenovo App Store.
Oddness: unless you use Airplane mode and then re-enable WiFi, you will get information saying the most battery power is used by the cellphone standby system. This device has no cellphone, as far as I can tell.
As a factory fresh tablet, it is good as a note taker, ok as an MP3 player (but: 1] needs display to be darkened or you hear crackling, 2] not too good with FLAC), not too good as a video player (refuses to play some versions of .wmv files and several other more recent and popular formats are unsupported), the touch screen is only 2 point, and the default keyboard interface seems to have real issues with sensing slow motions such as when I'm highlighting words in a text editing setting. All such editing situations, not just one app. Yes, even after touch screen recalibration.
All said, it is a decent device for its release date, is a bit dated now, and I like the form factor as it fits snug in my back pocket.
If I had to buy another tablet to replace the A1, the Matrix One 7 has ICS, 5 point capacitive screen and comes rooted.... for $60 right NOW. In a few days, it will jump to $120.
